Welp! Looks like I will be returning the product. Unfortunately this is a disappointment. I received the product today and opened it. The box inside the main box was wet. The packaging for the sprayer appeared to be cut on both sides. When I opened the box, the sprayer was used and had some wear and tear already. The accessories under the cap was also wet with residual water in the tank. I have to return this item because I don’t know what kind of chemicals was used before hand. Such a disappointment!! Come on!!!

Bought the first one about 12 months back, it lasted about 10 months, before it wouldn’t take a charge, so we bought the second one, two weeks into it the hose split in two. No problem I think I will take it off the first. Bought the third as a back up unit, it arrived the day the second unit stopped working. Quickly put the third one into us and it lasted 2 days and liquid is leaking out all over inside, figure once again hose on new one has split inside unit! That’s it I’m finished fixing this crap.Fool me once shame on you! Fool me twice shame on me! Fool me the third time NOPE back this goes!

The two things I dislike about pump backpack sprayers is the awkwardness of pumping pressure up in the tank and the too brief period after pumping the tank that you have steady, sustained spray pressure. This product solves both problems. No need to pump and the pressure stays consistent through out it's use.I had thought it might be unwieldy due to its dry weight of nearly 18 pounds (much of it due to the lead battery). Filled with 4 gallons of water that comes to around 50 pounds. After using it more, however, I have decided hat I would rather tolerate the weight rather than have to remove it from my back, refill it and return it to my back four times.I bought this product almost two years ago. About one month ago, I was going to use it to spray some weed killer and noticed the pump was not working. I was afraid the issue was going to be an expensive battery, but a $10 switch from Ace Hardware did the trick.

We bought this product to water our plants after using a watering can for quite a while. So with little to compare to....we were pleasantly surprised! The flow of water is perfect in my opinion. I read some previous reviews about broken parts or bad nozzles but that wasn't my experience at all. The onlyyy setback I see with this product is the weight. And realistically, it is to be expected for an electric sprayer. Luckily, once you get it on your back, it is comfortable. I, at first tried to water just carrying it and setting it down to spray but that's clearly not how it's intended to be used. Overall, good product and would buy again.

Read this with a grain of salt because I am seriously displeased. I RARELY write a negative review because I figure if it is working for others, great. I don't want to tank someone's business. If you read the other reviews, you'll see that this works well for most of the people who bought and reviewed it It did not work well for me. Customer Service: I posted two questions for the seller 3 days ago in preparation for use. Got nothing. The sprayer was all good until I got to the wand. Spray was going out the nozzle, and leaks were coming back me. I stopped the spray that was coming back at me with double "O" rings. Shouldn't have to do that. I tried every nozzle. You can switch nozzle, but you cannot adjust these. In my cheapo pump unit, in my hand held spray bottles, I can crank down the nozzle to get a mist or open it up to get a stream and everything in between. With this, you get the nozzle. I am spraying some nasty stuff to kill rampaging blackberry vines. Each of the nozzle gave me a LOT of mist. I cannot have this the poison I'm spraying drifting around my family orchard or the commercial orchards on either side of me turned into a mist. I need to be able the spray to be heavy enough not to mist. I tried to figure a way to decrease the pressure and failed. I tried hooking my cheapo unit wand up to this unit, but I could see this unit has fine threads and my cheapo unit has course. I was ready to fall in love with not having to pump, but two hours later, I packed it away. I didn't spend this much money to have to adapt and make do. If the manufacturer or anyone else can tell me what I might be doing wrong, I'll rewrite this.
