FlowZone Storm 2.5 Battery Powered Backpack Sprayer - Variable-Pressure 5-Position Electric Lawn & Garden Sprayer - 2.5 Gallon

Not sure why I waited so long to get this. So easy to use and very reliable. Haven't had any issues with it. Battery always gets me through the jobs.

Works great a real-time and labor saver.

Tank holds 3 gallons and a bit more. Seems most people will struggle using the larger tank model due to weight when full. I recommend this 2.5 gallon model.Seems to go 10/tanks per charge.I wish they'd let the back straps be mounted on either side to accommodate left and right hand useWill leak from top vent so keep upright.The performance of this product makes it useful for orchard maintenance as well as cleaning in some cases where before I'd use a high pressure gas powered pump.

Liked the veritable flow and battery life. Love the harness. Perfect size to carry.

OK, first let me say that the sprayer was purchased "Used, like new." When the sprayer was received, I first noticed that it was not in the original packaging, which was a red flag. I then noticed that there was some green residue on the sprayer, which indicated that it had indeed been used. Still, being that the flowzone has such great reviews, I have no issues with someone who may have filled it to test it out. HOWEVER, as I began inspecting the sprayer, I realized that the unit was shipped with no instructions, no nozzles (item is supposed to come with 3 nozzles) and no battery charger! I had to go online and purchase a 40$ charger, and will not be able to test the unit until the charger comes in. In addition, I will have to purchase nozzles for the sprayer. Once the charger comes in, I will test the unit and update the review, but even if the sprayer works, the best I will give it is 2 stars due to missing items at shipment.

Finally, a backpack sprayer that works as advertised! I can't say enough about this sprayer. It's quiet. Powerful. Not too heavy for a woman when filled with 2 gallons. Battery life is great. 5 stars.

As DIY lawn guy I can fully endorse and recommend this backpack sprayer. Included are several nozzles including stream and spray. The nozzles are easy to swap out on the fly. The straps are comfortable and adjustable with a chest strap for extra support. The included battery charger is fine, not a quick charger though. While there’s dual power available, a nice feature, I usually only use the higher power setting. It’s nice to know there’s options for high or low power though. Be careful when putting on the backpack with a full tank as it’s quite heavy and awkward. I was a little unaware of what I was doing and had to tie my shoe with the tank on and as I bent over the water in the tank spilled onto my back but I think this was an operator error.

FlowZone makes a great pump and spray wand assembly for their backpack sprayers. But, the tank always ends up cracking and leaking mixed chemicals. They need to strengthen the mil-thickness of the tank.
