  • Very useful
A little difficult to put together, the pictures were blurry and only black and white. But once i got it together, it works great. The shoulder straps are cheap, but it works. Good value, but not great quality.

  • Perfect product, great value, assembly instructions are a fail.
This backpack sprayer far exceeded my expectations. The light effort it takes to get a perfect amount of fine spray to the desired location is just what I wanted. I have NO hesitations getting another of these or recommending it to a friend. However, the instructions for assembly were horrible. I live in Oregon, and this product is "Oregon", but the directions were from somewhere really far away. Get the sprayer! Be patient putting it together. ... show more

  • Able to spray a larger area in less time.
The sprayer works very well. My only problem was when I first used it, the shoulder straps pulled on my shoulders. Carrying 5 gallons was difficult. I duct taped some padding to the strap and it became more comfortable. The tank holds 20 liters (5.3 gallons) which can cover a large area. I was able to spray 4 acres in ½ a day. Previously, it took me 2 days to do the same amount of area. ... show more

  • Poorly designed, bad instructions, broke days after 2 uses.
Horrible sprayer. The instructions are overly vague. Watched a video and the guy doing the tutorial even complained they make it hard to understand the instructions. For the price, having 2 components rely on cotter pins thinner than your teenage girlfriend is just embarassing. Wish I could get my money back but not bothering. Buy a different sprayer! ... show more

  • It kills weeds with the proper mix
The plastic wand is not very durable, I bought two of the sprayers and just went ahead and bought the metal wand to go with them. Plastic wand didn't last long.

If you buy, it go to you-tube there are numerous videos....poor instruction in written, diagrams and pictures, lots of extra washers, o rings etc. doesn't say why, some don't even look like the fit this unit. My skills are way above average so beware...... ... show more
