    You never know what kind of quality you'll get with a 4-in-one item, but this machine is proving to be a top-notch buy. The air fryer function takes longer than the counter unit, but the quality is the same without the air fryer smell. The toaster setting also takes a bit longer. These setbacks do not bother me. I made a pizza in the oven setting and the crust came out perfectly. I've used the microwave function several times and it heats my items quickly and evenly. Overall, this all-in-one machine has been a great purchase. I'm loving that I have more counter space now!

    Great replacement for large kitchen oven during the Arizona summer, or anytime of the year. Have tried the microwave, bake, broil and air fry. The air fry was ok(took much longer than oven baking fries with same result). Haven’t used toast setting. But all other methods are great.

    Great diversity in one
    [This review was collected as part of a promotion.] I love the concept of all the diversity of cooking methods in one appliance. The air fryer definitely makes great tasting chicken and fried foods without the heavy grease which is awesome. It toasts great as well. I have found the general microwaving utility a bit confusing and more complex than a standard microwave oven. I would like to see the general operations a bit easier to use. However, for everything in one, it does a great job at each cooking method.

      [This review was collected as part of a promotion.] I will start off by saying that I'm absolutely impressed with this kitchen appliance! I love that I can use The Galanz 4-in-1 for multiple cooking purposes. My favorite thing about this kitchen appliance would be how quickly I can heat up food items and also how perfect fries come out when using the Air Fry setting! This product is large and well made but very easy to use. I really like the style and sleek stainless steel design.

        Sleek look!
        [This review was collected as part of a promotion.] The Galanz 4-in-1 is so modern and sleek looking. After taking it out of the box and setting it up you get to really take a look at all the options this machine has to offer. A microwave, a convection oven, air fryer and a toaster oven. It gives you all the tools you need for each option such as air fryer basket, turntable and silicone mat for microwave, all of them easy to clean. The first thing we made was a frozen pizza. Its nice that it gives you preset buttons for simplicity and also gives you easy to cook reference times on the inside panel for convenience. The pizza definitely cooked quick, there is not a light to see from outside so you will need to open the door to check on it. We also used the microwave option to make popcorn. It was much quicker than using my original microwave. I also plan on using it to make air fryed wings and french fries. My kids love fries and chicken so this is a convenient one stop machine. It is rather large and does need 8 inches from the top and 2 inches from the sides for ventilation so you need to account for that when looking at space. It replaces my appliances into just one stop area. It is perfect for my basement kitchenette that doesnt have space for large or too many aplliances. Overall, it is a great looking machine with so much to offer.

          What a Game changer
          [This review was collected as part of a promotion.] This right here is definitely a game changer in the kitchen, I could go on and on about this product. There is so many good things about it. I can't believe it is 4-1 multifunctionality. It's an air fryer, convection oven, microwave, and toaster oven all in one! It has plenty of room to make your perfect meal for the family. It can make so many healthier meals when air frying. This thing has sensor cooking so your food is never under or over cooked. The toaster is awesome to, I have made toast a few times and it comes out perfect, nice and toasty and you can set it how light or dark you like your toast. Cooks bagels also to a perfection. It comes with a silicone mat, baking and roasting pan, ceramic shaft, and air fry kit. It has an easy to read display screen and a variety of pre-set cooking settings. It is very easy to clean also after using. This product is made very well and I'm sure it will last a long time. I have made a couple pizzas in it already but the first one I went by the pre-set for pizzas and it cooked to long, so for now I just cook about 9 minutes. Chicken nuggets, fish sticks, and fries come out so good after air frying them. I love just all the features about it. Nice design and stylish. I really like it and with this 4-1 I can have extra counter space by removing my toaster and air fryer. I really do recommend this product if your are looking for a great appliance that does so many things in one.

            Amazing Appliance, So Many Functions
            [This review was collected as part of a promotion.] The Galanz Toastwave 4-in-1 Functional Oven is a pretty amazing appliance. First of all, it's very nice looking. A little big, but fit easily into the spot where my I kept my previous microwave. And it really doesn't need a whole ton of open space on the sides and top- just 2" on each side and 8" on top. First of all, I'll say that I do have a couple of issue with it, so I'd probably give 4.5 stars if I could. But I didn't feel like the cons outweighed the awesome stuff about it enough to give it a 4. So let me get the cons off my chest first, just to get it out of the way. There are a couple of things I am not crazy about. The instructions are a bit too basic. Not even that so much, because they do explain how to use every function and they're generally easy to understand. But they lack "tips" to get you started with actually cooking something with it. (You know how most appliance instructions will have some recipes or hints.) And they lack good explanation of using the accessories. Like you get this silicone mat with it, and it doesn't really explain what it's for, other than in the section of the instructions related to the microwave, it shows the mat at the top, under "accessories." It doesn't say whether you HAVE TO use it all the time when microwaving, or just what it's for. And air frying. It tells you to use the air fry rack that comes with it, and how to set the time, but no hints about how to actually air fry foods. Like, do you add any oil and if so, how much? I guess it assumes that the user is already experienced with air frying, however this type of air frying is different than what most people would've have used with a dedicated air frying device. I did find a video on YouTube that is a little more beneficial, as far as instructions, and it's done by the company itself. So that helped. And YES, you do have to use the silicone mat all the time when using it as a microwave. I'm guessing that it's maybe because the turntable is metal and may get hot enough to crack the glass plates or dishes you might be microwaving your food on/in? But that's just a guess. So just use it! And then the one other thing that kind of annoys me is that the way the turntable is made. It sits on the base via a molded shape in the metal piece in the middle. The problem is, the indented spot in the turntable is a little bigger than the base, so it's doesn't fit completely tight and so, it has some jiggle room. The base piece that it sits on it like an unglazed ceramic material, and I can see already that it's got rubbings from the bottom of the turntable on it, and the turntable has a few scratches from rubbing the wrong way on that piece. I've noticed a clunking sound when it's running, and I'm guessing that's what it is. And I've been careful to be sure that I have it set in there just right, so I'm not sure why this is an issue. Lastly, my experience with toasting a bagel, seems that the toasting function takes a little longer than with a regular toaster. (I expand on this more below.) Okay, so those couple of things out of the way, let's get to the awesome stuff. This thing has more features than I will probably every use. It's pretty amazing, all that it can do. But it's different than other toaster ovens and counter top ovens I've used. There's no oven rack and everything is cooked on the non-stick turntable. Pretty neat design. So when you make toast or bagels, you lay them right on the turntable. They do toast evenly, but it takes a little longer than a regular toaster. I toasted some bagel thins and selected "1" even though I had 1 1/2. (I figured since they were the "thins," they wouldn't take as long as a regular bagel.) The time came up as 8 minutes and I though "No way." I kept checking them, and it probably didn't help, me opening the door so many times, but I finally took them out at 6 minutes. They were toasted, but not really browned on top, so I probably should've left them for the full 8 minutes. But it's very even toasting and it is nice to get rid of a separate toaster, even if it does take a little longer this way. And because they're laying right on a solid, nonstick surface, there aren't crumbs falling everywhere. And no crumb tray to keep cleaning. I like that! The turntable is just the right size for a 12" frozen pizza. How perfect is that?! I don't have one on hand in my freezer, but I can't wait to give that function a try! (If we weren't under the stay home orders right now, I'd have run out and gotten one already.) The pizza function has 4 pre-set temps you can choose from- 400 (default), 425, 350, 375. Which is also neat. So, what else does it do? Well, it bakes, broils, has a convection oven feature, and of course all of the microwave functions. The turntable locks, if you want it to sit solid in one place rather than spinning, while baking. Also a nice feature. I am planning on cooking a small roast in it this afternoon, but without it having an oven rack, I'll have to use a baking dish that fits on the turntable. Which is okay because I still find the whole design of cooking everything on the turntable pretty neat. Think of how when you use your oven, how some things overflow and drip down and you have to clean that. Everything with this will stay on the non-stick turntable. No dripping below. Then there are the microwave functions. Wow. This thing actually has a sensor cook setting where you can tell it what you are microwaving, and it senses by the steam generated by the food, when it's done. It will do that with cooking and also with reheating. I've never heard of such a thing until now! Of course you can also use it like a regular microwave, choosing the power level and number of minutes. I used it to reheat some meatloaf, just manually choosing the number of minutes, and it reheated it from frozen in a lot faster than my previous little microwave. I was pretty happy with that. Yes, there is a popcorn button. As well as the +30 secs button. (Which I use a lot.) And a child lock. Also, the clock is easy to set, and you can use the timer just as a timer, even when not using the oven or microwave. I read some other reviews that said the clock didn't keep good time, but so far it's kept time for me just fine. The best part is the big, round, silver button you see in the pics. That button basically does it all. At first it looks intimidating, with all of the buttons to press and the big silver button that dials, and also presses. But it doesn't take long to get the hang of it. So much of it is pre-programmed, as far as times for certain foods. And, there's a timetable for cooking certain foods right on the panel when you open the door. All in all, this is a beautiful appliance with so many amazing innovations. And being able to use it to do some baking in place of turning on my big oven will save on electricity. I would definitely recommend it.
