Leaking on handle
I bought one of these about 2 weeks ago and have been meaning to write this review but ever since the first day I opened it, it leaks at the handle, and spilled all over the straps. I was really hoping it would workout, but I guess I'll have to return it.

    Very Good Sprayer that gets the job Done
    This updated Ryobi sprayer worked very well with one EXCEPTION. The control dial will vibrate to the OFF position when the control dial is set at a minimum spray setting. On my first use of the sprayer, I had to keep my hand on the dial to prevent the sprayer from shutting off when spraying weeds using a minimum setting. This is not a problem when the dial is set to medium or high. See my simple fix for this problem I listed below with pictures. Ryobi needs to FIX this problem which would make this an Excellent sprayer. I had no problem with leaks or any other problem. I found the fill marks on the tank to be close to the correct gallon marks when the top of the square mark is used as a reference. I used 2 tank full (8 gallons, which is not heavy once you get the sprayer strapped on) of liquid to spray a very large gravel driveway which took very little time compared to using a 2 gallon pump up sprayer and did not drain the included battery much as when I put the battery in the included charger, it fully recharged within 15 minutes. Note the drain hole is recessed and is on the opposite side from the hose. I had no problem using all the liquid as long as I kept the sprayer level or slightly leaning to the left. If you let the tank lean to the right which happens as you are spraying and pulling on the hose which offsets the tank, there will be several ounces of liquid left in the tank. The instructions said the sprayer came with replacement seals. There were no seals included in the box and I contacted Ryobi and they had a set of replacement seals mailed to me. Note the seals are for the wand and spray nozzles, the pump is not user serviceable. The fix I did to keep the control dial from moving was simple. I punched out a thin rubber gasket with an O.D. of 1.5 inches / I.D. of .5 inches and put over the control dial shaft so the gasket was between the control dial and the tank (see pictures of dial and gasket). This provides just enough friction to keep the dial from turning but the control dial was still very easy to turn and does not interfere with the operation of the sprayer. From looking at how the sprayer control and the switch that controls the pump speed is built, not sure of another easy way to fix that problem other than modifying the actual control switch. Regardless, Ryobi needs to FIX this problem to resolve the issue with the pump turning off.

      One of the best chemical sprayer for homes
      I bought this chemical sprayer few months back for my front and backyard. I first thought the battery (2AH included) won't last long but I was wrong. It lasted over 30 gal before I had to recharge the battery. The plastic body was durable which I believe it will protect from at least 10 drops on a concrete floor. Their were few downsides (but not significant to change my mind).... 1. Not so easy sprayer cap on the top. 2. Flimsy plastic sprayer rod. - If ryobi switch the rod to stainless steel or some other durable material than cheap plastic it will be great. 3. Not so translucent Plastic Water tank. - make it more clear so the user don't have to tilt or shake the tank to know the amount of water remaining in the tank. If the water tank was also detachable (the wash it) it will be a huge plus too.

        Double Trouble
        [This review was collected as part of a promotion.] My sister began crying when she got these because it now makes her job and business a bit more easier and she also looks cooler and more professional when arriving to a new client. She is now more than motivated to get to work. She just started a new cleaning business and ryobi was on her wish list after reading all the reviews and on youtube.

          Great spraying unit
          [This review was collected as part of a promotion.] Purchased this to apply liquid fertilizers to the lawn, it works as it should, no issues. The fan tip sprayer is outstanding. The only problem I have with the unit, is that as others have mentioned, the gallon measurements on the tank itself is way off.

            Best Value for a sprayer
            [This review was collected as part of a promotion.] Bought this to apply micronutrients to my lawn. Works great, best value I've found. Simple to use and assemble. Only negative is the plastic wand, it works well but wish it was metal. I did modify it by painting the gallon numerals on the tank (and the 18V symbol)

              Inaccurate marked measurements on tank.
              [This review was collected as part of a promotion.] First, Ill say this sprayer is a great value. It works very well, and needs nothing extra out of the box, except a bit of time to correct the measurement errors on the tank, which is kind of a big deal, since even the cheap sprayers seem to get it right. Without that issue, this could have been a slam dunk by Ryobi. Mine was off almost 1/4 gallon low at the 1 gallon mark, 1/3 gallon low at the 2 gallon mark, right on at the 3 gallon mark, and about 1/8 gallon high at the 4 gallon mark. This is going to the top of the molded rectangles around the numbers embossed in the tank. Both of my sprayers are identical in that regard, so I doubt I just got a bad example. After spending some time confirming this, I went back and filled using accurate measuring cups (1 gallon size), and marked my tanks to be accurate. Pictures added. One extra step that took some time, and really shouldnt be needed, except that the manufacturer couldnt be bothered with checking the tanks before mass producing them. Its still a good sprayer, but that takes away from the value.

                Inaccurate molded measurements
                The sprayer itself is great, especially for the price, but it could have been 5 stars across the board if someone had taken just a little more time in the design stage. The issue, and it could be a big one for anyone needing even remotely accurate measurements for water volume who hasnt checked, is that none of the markings on the sides of the tank are correct except a couple. The only one on mine that is accurate is the 3 gallon mark (and likely a similar Liter marking on the opposite side, though I didnt check those because I dont measure in Liters). Fill right to the top of the molded rectangular section around the 3, and thats 3 gallons on the dot. To get one gallon, its between the top of the 1 gallon mark and the next hash. The two gallon level is slightly above the 2 gallon molding (about 1/3 of the way between the molding and the hash), and the 4 gallon hits right at the top of the molded 4, below the molded rectangular section. Other than that, its great. Id think that a company putting out a sprayer would have at least checked this out before sending a product to production, but apparently not, because both of my sprayers are exactly the same. For the cost savings over the other sprayers, I guess its worth it to have to measure it all out and mark it correctly once, vs paying considerably more for a correctly marked sprayer.

                  poor customer service
                  I purchased my P2806 sprayer in store got it home and started to put it together and found the wand was missing the locknut that holds the wand to trigger assembly , I called their customer support and had agreed instead of returning whole unit back to the store RYOBI would just send me the part that was missing , No big deal I had time before I really needed to use the sprayer well nearly a month latter I received no part called RYOBI again and they said the part wasn't available and if they ordered it from china it could take 6 months . I was trying to be practical and avoid returning the whole unit I explained the wand parts on the sprayer are pretty generic and i could get them online for cheap and could get a RYOBI genuine wand for a P2804 Sprayer for $11 which is the same they didn't care . In short I purchased a replacement part and love the sprayer it is great for residential use pressure and battery life are great ,but hate the impracticalness of the customer support sometimes you need to think outside the box of the trouble tree steps of answering the phone to make a customer happy.

                    First of all let me say you will likely not find a better powered sprayer.... but...there are issues. The thing is built like a truck, robust, and it does its primary mission well... spraying. The variable speed adjuster is just genius. The fact that you can add this tool to your other +1 18volt Ryobi tools without paying for another charger and battery is very nice... there are like a hundred other Ryobi +1 tools to choose from. Now the not so nice: 1. the screw on lid is all but impossible to remove or put back on... I finally gave up and put Vaseline on the threads to reduce the friction. 2. The much touted free spare seals are NOT included.... instead there is a flyer that states "free seals for life" for registering the tool.... that's nice except when you go to the site to register, the sprayer I have is not listed... in fact if you try to look up the sprayer by the supposed model number, it comes up with a weed whacker.... so, no register, or free seals. 3. While there I followed the other side of the flyer to do a review and possibly win a Home Depot gift card... no place to review, the help line was closed. 4. The model number, by the way, is not listed anywhere on the sprayer or the packaging... only on the packaged manual. 5. The shoulder straps are heavy duty and well padded, except you have to run the adjustment as far as possible to get the padding over your shoulders where it is really needed... this thing is heavy. 6. On the bottom of the shipping carton where the technical data is displayed, it clearly states that the Ryobi 18 V One + is the intended battery for this sprayer... a side note below the bubble states that "for best performance use with a Ryobi 40V 4 Ah battery"... this sounds downright dangerous to me.
