Favorite electric sprayer
Style: Battery & Charger Included
Lightweight and ergonomically designed sprayer. So far I’ve had no leaks. I don’t fill it past the max fill line or tip it over, which will cause it to leak. The Straps it comes with aren’t the best cushioned, so I ordered some but that’s optional just my personal preference. Great buy

Good Sprayer
Style: Battery & Charger Included
I bought this model because of the options for using other manufactures batteries. The OEM battery performs very well. After 1 1/2 hours of use the battery is still almost fully charged.

A must have! No more pumping
Style: Battery & Charger Included
Man I love this!! No more pumping. It shoots so far too. I wish I got this a long time ago for my commercial landscape business. This thing is now my go to sprayer

Very pleased
Style: Battery & Charger Included
So far I am very pleased I have used it for a couple of weeks and nothing negative to report works as advertised. I must say don’t leave solvent in it for extended periods and flush it out with water after every use.

Flow Zone is the best.
Style: Battery & Charger Included
By far the best sprayer that I have ever used. It has a wide assortment of pump speeds, and all three essential nozzle tips. The shoulder straps and harness make carrying 4 gallons of liquid as comfortable as it can be.

Good sized and built rugged
Style: Battery & Charger Included
Good sized sprayer, not too large or bulky and heavy when filled, to be a struggle to get on after fill up. Of course, it doesn't last as long as a larger size back pack sprayer. No leaks and sprays very well with the assorted tips. The extra large size handle and screw top is great, makes it oh so much easier to undo after it's empty, as sometimes there's a vacuum in the tank and some negative pressure to open up. It's built with a rugged feel to it and holding up well under abuse with monthly sprayings of my front and rear yards.

Exceptional Flowzone quality - this is unit excels at spot spraying
Style: Battery & Charger Included
For those that don't know, Flowzone is the best in the business at backpack sprayers and this new unit is no exception. However, it may not be the unit for everyone. With a constant 40 psi, its not the most powerful flowzone unit, and you might need to upgrade to a higher priced unit if you have more extensive needs. Where this unit shines is bringing an amazing flowzone unit to the market at a more reasonable price point and absolutely crushing the spot spraying needs of most homeowners. That said, it may still be a lot better than many of the competition's units. For instance, I also have a ryobi sprayer, and while that advertise 90 psi, in practice, once you add some fancier teejet nozzles on that unit, the psi drops way down, so you may very well just be better off with this flowzone anyways. (do a youtube search and you will see what im talking about)
