What Customers Are Saying

Customers praise the sprayer's lightweight design, intuitive operation, and excellent value for occasional home tasks like weed control. Most appreciate its easy assembly, compact size, and straightforward pump mechanism. However, a notable portion report durability concerns, including premature pump failures, pressure retention issues, and leaking seals after minimal use. Some mention limited spray range. Despite these reliability drawbacks, many still recommend it for light, short-term jobs where affordability matters more than longevity.

Uncertainty over use

Would Not Recommend

Instructions say to fill with water to the fill line. But if there is a fill line, it certainly is NOT labeled as such. There is a round detent near top of the cylinder but there is no print or anything to indicate it is the fill line. I also found it tricky to rotate the pump handle to a stop on the black plastic cap. The handle often does not stop. Some mixed insecticide spilled out of the black plastic and got on my hands. Once I got past these issues, the sprayer worked okay.

Generally good, but needed some adjustment

Would Recommend

Generally good sprayer. Thick plastic so I think it will stand up to pressure. The hole for the hose was very small, but with a little help from my drill everything is working well.

junk - won't pressurize on 2nd use.

Would Not Recommend

Worked great first time. Pressurized just fine. Used Vinegar solution mixture to spray weeds. Left half the liquid in the tank. Came back 5 days later to finish the job. The pump won't pressurize the container. No serviceable parts. Junk.

Garbage

I purchases have not even been able to use it will not spray. I called project source hoping that maybe they could send me another one since this one will not work and he wants me to return it to the store. I'm on crutches and it's very hard to get around dude. I'm waiting for surgery and they were no help at all so that was a waste of money. I do not recommend this sprayer at all. it's garbage

This is the bare minimum for a tank sprayer

Would Not Recommend

This unit is very light duty and meets the minimum requirements for a 2 gallon sprayer. The hose and wand are the worst part. The hose is short and the wand is shorter. There is no way to use universal wands or hoses due to the proprietary connections to the tank and the wand. This is ideal for a one-time user who needs it for a project and then throws it away. The pump builds pressure slowly as well.
