Melted while holding it
This trimmer did really well for a good time, but ultimately it didn't hold up. Using it today it melted and started bending in half right at the motor vents.

    I was tired of gas string trimmers
    Worth every penny, not sure if i will ever have to go back to gas string trimmers again. I was tired of mixing oil and gas or having to buy pre mixed fuel all the time. The battery that comes with it is pretty decent, but I do plan on purchasing a 6ah battery as well. By far the easiest string replacement i have ever done with any string trimmer, ever. I recommend this to anyone and everyone!

      Good value, high quality tools, low quality hardware
      I already owned a Ryobi 40v lawn mower and I was grateful to find this bundle. It was a good price for two more tools and another 40v battery. The weed trimmer is sturdy and easy to use. The leaf blower is easy to use and has great power. Unfortunately the plastic bolt that holds the leaf blower handle in position broke within ten minutes of taking it out of the box. Thankfully it's a standard 3/8" bolt hole, so I went to the hardware store and got a 3/8"x4" carriage bolt, a washer, and a wing nut for $1.86. You could probably use a 3.5" or even 3" bolt instead. Overall it's a good set, but be aware that this plastic bolt is very flimsy.

        piece of crap
        Dont buy it. Unless you like prodicts that work for one time and then break. Piece of crap. It worked awesome until it decided to spit the head off and then it was ruined. Good luck getting service. Two of the four tabs that hold the string trimmer head on are permanently “locked out” which doesnt allow the string head to be placed back onto the trimmer

          If you are looking for a blower that will (presumably--I've only had this blower for about 5 uses...
          If you are looking for a blower that will (presumably--I've only had this blower for about 5 uses now) work year after year without having to prep and store it for the winter, then this is your blower. I've had two gas blowers over the last 20 years, both of which required being emptied of gas for the winter and having Sta-Bil run through them. Then every few years rebuilding the carburetors so they would start, idle and rev properly. And even so, one of these blowers was easy to start but couldn't be restarted when warm, and the other couldn't be started when cold, just when warm. Aargh! The Ryobi blower is truly simple--there is just a battery to keep charged with no gas mess, no storage chores, and no carburetor rebuilding. The battery holds a charge for long enough to blow all of the areas on our two acres that I usually clean with the gas blower, and that is using the "turbo" setting for most of it. The blower has enough power to mimic the gas blower's performance (while on turbo mode), and the regular mode is good for our front porch (it won't destroy the potted plants in this mode). It would be nice if the turbo button had a lock on it (you have to keep your thumb on it for the extra power), but other than that there is nothing nicer than pulling the blower off the shelf, slapping on one of the 40V batteries, and going out and cleaning up!

          Great tool with one flaw (for me)
          So I primarily use this for doing maintenance of the riding trails around the barn. I have an excellent Stihl gas trimmer but it's so loud that you can't really work around the horses with it. This is basically as loud as a loud fan, so no need for hearing protection (definitely eye protection). Since the stuff that grows on the trail is super tough, I swapped the string-head out with the bladed brush head. Now on my Stihl I have used every brush blade out there (the Y shaped one (meh), the chainsaw disk (ugh) and the circular saw one (best). I will say these little plastic blades did surprisingly well (although both snapped after several hundred yards of heavy stuff (but only about 1/2" snapped off so totally usable) So first off battery life? Well I constantly see reviews where people imply that they cleared all of Kansas' wheat fields on just 2-dots of battery... I mean I probably was able to clear 200 yards of heavy brush 6' wide before it stalled out. No complaints there (carry a second battery). The motor did not get hot. The biggest flaw was in taller grass the stalks wrap around the transfer case and get between the 2 halves. It is super tightly wound on there (see first photo) (a knife is good to get that out of there) The trimmer would stall out from the friction of that mass of grass. Not sure why they couldn't put a little shield on there (I may 3D print one in polycarbonate). Otherwise this thing was fantastic. In case someone is wondering why I don't just mow it, I've found that if I don't knock it down with the trimmer first the tractor mower can't chop it up effectively. Note in those photos the trail was chest high before hitting it with the trimmer.

            This Trimmer Is The King of Weed Eating
            Love the price and the quality. Easy to assemble and the most powerful battery next to what NASA has. 5 Thumbs Up for a battery operated weed killer that goes above and beyond. Balanced perfectly and met all my weed and grass trimming expectations. besides, I can use it for 90 days and if it does not function as indicated, I can return it to HD for a full refund. And so far, I have no complaints at all. With a full 15in cutting swatch, I'm finished doing my acre of ground in no time at all.

              Works fine until the handle breaks
              Been using mine for 3 years and out of no where the handle snapped off. Not due to abuse or anything of the sort.

                Great cordless trimmer with lots of power
                I have let the trimming of the weeds around my house and brick pavers in my landscapping get out of control becuase all I have is a corded trimmer which is a pain in the butt to use with that cord dragging around everywhere. Also the power was not the best as well even though it was plugged in. Decided to finally upgrade to a cordless, non-gas trimmer and I am glad I did. The timmer charges pretty quickly and holds power well, and the adjustable handle is very handy so you can adjust according to height and how you want to hold it depending on if you are trimming or just killing weeds. The power was the best part as that was my biggest concern, but this things packs a good punch and cuts through thick weeds. This is a great cordless, non-gas trimmer with lots of power for any job.

                  This is just what the doctor ordered! I am getting older and a recent hand injury has made it a challenge to start the 2-stroke Ryobi Expand-it power head. It is not fair to compare the power and speed of the 2-stroke to the 40 Volt battery. The 40 Volt battery is quieter and much easier to "start". The battery still had power left after I trimmed and edged my yard. Other reviews complained about the string feeder/loader breaking. I was able to put the old string trimmer on the 40 Volt. I have a new backup trimmer if the old one breaks. The 40 Volt is easier on my hand and better for the environment!
