I just got this sprayer recently. I do pest control for a living. This is a great sprayer so far, have only used it a few hours so far. It has a very good vertical spray distance and the extendable metal wand is nice. As far as longevity and how it holds up to abuse is to seen still. I am keeping my fingers crossed it holds up because so far it is great!

Love that this product comes with TWO batteries!!! The spray quality is decent. I love the options you get as far as sprayer attachments. I will say the instructions for the back pack strap attachment placement was a little confusing but I managed to figure it out. All in all I love it. I’d definitely purchase this again.

This sprayer set cam with everything that I needed to get started and spray some different areas in the yard. There are two batteries, which is very convienient. The backpack styling and back straps are very comfortable for me to wear, and easy to take on and off. The sprayer sprays with a lot of pressure, I have used the sprayer to clean off the decks, as well as using to spray on some fertilizer on our garden plants.

This backpack sprayer has made yard work so much easier! The two 2.0Ah batteries provide plenty of runtime, and the adjustable 100PSI pressure works great for everything from weeding to general garden spraying. I love the variety of nozzles and the dual wands—super versatile for different tasks. It’s comfortable to wear and easy to operate.

When tending to our property- using our hose has worked but it also has a lot of areas that I could not reach in keeping up with my plant irrigation areas. This year I decided to find an alternative method to achieve to get this accomplished simple and easily. After searching and comparing different types of systems- I found this one made by the store TASKSTAR store and decided that this looked like a promising solution and so I ordered this. Now that I have this home and have FINALLY gotten the chance to try it out due to (nice weather) and I have to admit this is a very incredible solution for my household. Very simple to use- not too heavy. Great results and I do not have any regrets based on the great performance. *Special features worth mentioning: -Battery Operated Backpack Sprayer -2.0fAh -100 PSI -(6) Nozzles are included -Weight: 10.4 lbs. - Dual telescopic Rods -4 Galloon (16L) All in all, I find that the designer or this battery pack sprayer did a very good job. I had no issues using this around my yard, ensuring consistent water coverage with the flexibility of this sprayer. Based on a positive experience, I would recommend this to other consumers. Thanks for reading my review. :)

I got this to spray fertilizer and pesticides in our property. ❌ -Instructions are not clear -Build. It’s an expensive sprayer so I expect high quality. The plastic is cheap, the cables compartment are open, no storage/bag to place the accessories. -Battery life is the same as other cheaper/smaller versions
