What Customers Are Saying

The product is generally well-received, with users praising its consistent and wide spray pattern, as well as the comfortable backpack design. However, some customers have reported issues with the durability and longevity of the pump, such as it failing to build or maintain pressure or the unit breaking down after a short period of use. A small number of users also found the sprayer to be too heavy when filled to capacity. Overall, the product appears to be reliable and effective for most users, though the pump mechanism may be an area for potential improvement.

Worked twice

Would Not Recommend

Not sure if this sprayer is just junk or if it couldn’t handle having indicator dye put in it, but it quit working after two uses. I can’t tell where I have sprayed most of the time, so to avoid over spraying I use an indicator dye in the weed killer. The first time I used the dye in this sprayer it just DIED! Very, VERY upset with this because now I’ll be back at the hardware store buying ANOTHER $80 sprayer…but it won’t be this one!

Works as it should

Would Recommend

Works great, wish it was battery operated because your arm gets tired pumping after a while if use.

Heavy without the water in it

Would Not Recommend

I would recommend that you only put in two gallons of water at a time. The system is vey difficult to pick up and get onto your back (sort of like a very heavy awkward back pack). I recommend that you only put in two gallons at one time. Safety first.
