          In no way did this sprayer come close to 3 stars.
          They don't even last 1 minute. Most come broken, leaking, etc. Even the Milwaukee service center in San Diego has to change locations every year to keep the angry customers at bay. Best bet, just get the 3 year warranty, buy about 10. That way you can just make 1 trip to Home Depot and return about 7 right off the bat. And careful what ya wear, clothes wise, this thing WILL leak all over you. YES!!I have run through about 10 of these. The last one I donated it to Milwaukee so they can figure out the chinese part.

            On my 3rd tank, now leaking.
            I purchased two sprayers in March of 2020. Two tanks, two motors. The backpack is fantastic due to the hip belt. Backpacking is one of my hobbies and I cannot understate the importance of a properly configured hip belt, with nearly all of the backpack weight carried on the hips, when carrying heavy backpacks. Everything about the sprayer is great, EXCEPT FOR THE TANKS. My two original tanks eventually leaked from cracks, a third I received from Milwaukee now leaks. This is a common issue.

              Tank leaks but can be fixed
              Bought a brand new one. Unsuprisingly the tank is leaking. I then spent ~ 40 min to fix it as I figured out it may require more time to get Milwaukee's replacement. Here is what I did: 1) remove screws on the tank's bottom to open the black base cover. There are four white plastic fittings under the cover. 2) Fill tank with some water to spot the leaking fitting (My unit leaks on fitting 1). Empty the tank 3) Unscrew the fitting by turning Part B counterclock wise while holding Part A in position . Yes, the two parts are seperated but water tight. 4) Add some layers of teflon tape to the thread ( I also added a thin layer of PTFE thread sealant) . 5) Screw the fitting back to position. 6) Refill the tank with water to check the leakage. 7) If no leakage, rotate Fitting 1&2's Part A to inward direction so that the whole back cover can be placed back Hope this helps

                Absolute garbage
                This thing is expensive and it's absolute garbage right out of the box. Leaking chemicals all down my back from inside the hose connection point at the tank. Just spent over 20 minutes on hold with Milwaukee and they hung up on me. I own many many thousands of dollars of Milwaukee tools and will never purchase another one. What a piece of crap. Clearly other people are having the same issue in Milwaukee is not willing to do anything about it. What a trash company.

                  Bought 2 units 3 hours apart - both leaked.
                  I loved the concept and really wanted to like this sprayer. Bought 2 of them today about 3 hours apart. The first one I filled with water and round up - leaked all over my truck and bottom of tank on hose side. Drive the hour back to Home Depot and picked up another one. Didn’t waste round up on this one - filled with water and what do you know, it leaked in the same a lot. I removed to black plastic on bottom to see it maybe something wasn’t sealed or hose clamped poorly - but it’s leaking from the plastic tank where the inside piece meets it. Oh well, I emailed Milwaukee - but no response yet. Guess I’ll have to find an alternate product now.

                    Internal components are cheap and break very easily.
                    I have purchased 7 of these backpacks, they lasted 1 1/2 weeks. The handle is the biggest issue, it leaks and the trigger spring breaks causing the pump not to turn off. Very disappointed in Milwaukee. I wasted a lot of money on this equipment, I do not recommend until they fix some issues.

                      Convinced a buddy of mine to ditch his manual pump and took advantage of the 2-pack deal while it was 25% off. He bought two high output 3.0 batteries so he'll never have to pump again. 5 stars!

                      Fantastic product as usual from Milwaukee. I’ve actually increased the efficiency of my weed spray mix as my previous sprayer for 2 gallons would only last about 30 min worth of spraying where 2 gal in the Milwaukee will last me 2 hrs straight or more. Only gripe is there is not sufficient padding on the shoulder straps for the weight of the fully filled pack.

                      I have a several hundred square feet of roof and pavement that I treat periodically for moss. I've been using a manual pump backpack sprayer that's tiring to keep pumping, so I thought this M18 sprayer would be a great solution. I'm an older guy and since the sprayer pretty heavy even empty I used it with only 1.5 gallons (12 lbs) of solution at a time.. The fact that the backboard is hard plastic doesn't help the comfort level. With the smaller amount of solution I got along pretty well and was able to climb the ladder to the roof and spot-spray the moss. I really appreciated the high pressure jet - I was able to spray under my 12' deep solar array and could spot spray a wide area on the roof around where I was standing. The adjustable nozzle adjustment is very sensitive - it's about a quarter turn from jet to mist. The handle has two locks - one to lock it open and one to lock it closed. There is a basket strainer under the tank cap. The holes in the strainer are larger than the holes in the solution intake at the bottom of the tank so particles could get through that would clog the intake. Although it's not shown in the instructions, it's pretty easy to remove and clean the tank intake when the tank is empty - a quarter turn counter-clockwise releases it. The hose and wand keeper are on the right side. I'm left-handed so I have the hose draped across my front while spraying, but the hose is long enough this wasn't an issue. The pump and hose are built into the tank and the motor that drives the pump is in the base. When it quit spraying and the tank was level, there was still some solution in the tank. I used the tank drain to empty the tank and there was a little more than a pint of solution left in the tank. On the roof I found that if I leaned to the left (since the intake is on the left side of the tank) I could drain the tank down to a couple of tablespoons of solution left. After spraying 3 gallons, the XC5.0 battery I used was down one light on the battery gauge. The battery compartment is large - I was able to install an M18 HD12.0 battery in it, but won't be using it since I don't need the sprayer to be any heaver.
