Well bought this for side jobs.But didn't use it right away. Shouldn't have done that. On first use it was shooting water and bleach out the side of tank at a seam. Now stuck with with a loss of money and time. Missed return date. If you buy make sure you use or try it first day.It leaks. Not just a slight inconvenient leak... you know one that leaks down your back and soaks your shirt and pants. The wand also leaked after the first season. A waste of money.Used for weeds works great I will recommend it to anyone.Very a easy to set up.Great for the price, was a little heavy, but much easier to lug it around than working a manual pump.Worked very well on its first job. Ran flawlessly. Strong spray. Was a little heavier than I thought with a full tank, but got used to it.I bought this sprayer so my left arm wouldn't get sore keeping the sprayer tank pumped up enough for even spraying pressure. At first this sprayer seemed heavy because of the battery. But the back straps are placed so the sprayer hangs and stays naturally in a most comfortable position. The only drawback to this unit is that you should turn the pump on before you put it on your back--my arms can't reach around to turn it on or off. But that really is not a problem at all--the pump runs all the time anyway providing a constant, uniform spray pattern. My only recommendation to a new buyer is before you put any chemical into the sprayer, just add water, turn on the pump and test the different nozzles that are provided so you can get the spray pattern you desire. Overall, this is one mighty fine unit that you can spray many tank fills without any undue physical pain or issues. I fully recommend it over any type hand pumped sprayer.
