Would buy again , works better than expected and better than advertised! Only improvement I would like to see is a bigger capacity (due to the size of property I have). But more than enough for the average home area. I filled three times and the battery was still over half capacity.

I might be a little biased as I own several Greenworks tools. They are light (but not cheap), work exceptionally well and last a loooong time. I have a hedge clipper (fantastic), line trimmer, leaf blower, chainsaw (amazing) and until recently, a mower. The mower was 11 years old when it died and that was my fault. Stupidly, I rinsed the bottom with a garden hose. I could lift this twin blade marvel with one hand. The sprayer is equally well designed, with quality components. Will be applying lawn pre-emergence. Of course, calibration is required. Check out Average Lawn Guy on YT. I got it done on the first pass. At a walking speed of 81 steps per minute (24" step, using a metronome app) the sprayer delivered 1 gallon of liquid on a 1,000 sq ft patch in 2 and a half minutes. I can do my entire 10,000 sq ft lawn in 25 minutes. The fan tip, at about 8" from the ground, produces a consistent and even swath of liquid, about 2 feet wide. The sprayer is light, quiet and super comfortable, especially compared to other backpacks I've used. It has both waist and chest straps that keep you snug and comfy. There are so many other choices for sprayers. It was tough to make a decision. I feel I got lucky with this one.

Love these sprayers. First one lasted about 25-30 applications @ 3 gallons. Then it just quit. No way no where to get it repaired. So I just bought another one which was on sale. Hoping to get more use but we’ll see. Worked out to $3-$3.50 per application good enough for the work I use it for. Very comfortable, easy to use with plenty of spray patterns available. 40v batteries provide plenty of time and it’s fast and easy to put in another one.

I have many Greenworks products (lawn mower, edger, chipper, blower, 2 chain saws, etc... probably 8 or so) and they work very well. Have always been very pleased (5 stars) until this product. This product is easy to use and cuts the time of applying chemical by a marked amount. Battery life is very good. It is a huge time savings and worth the money except for the following. The lid leaks and it leaks badly in certain situations. I have twice been doused with chemicals drenching my lower back while using this unit. The first time (round up) I thought I might have spilled some on the sprayer when filling it and then it transferred to me. So I rinsed it and kept using it. I've used it many other times without leaking. Then yesterday, I was drenched again. I was using tenacity with blue marking die and immediately after I put it on (before I started spraying) I found my shirt and lower back drenched in blue die. Probably 1/2 cup of fluid made it out the vent. I stripped and washed, then traced the leak through the dye to the vent hole in the lid. The hole is small so sloshing in the tank doesn't cause a leak, but if you fill to the 4 gallon mark and lean it a little (no where near horizontal) in the wrong direction the fluid comes out into the lid and then rolls down the side and/or rear of the sprayer (and you can't see this if it is on your back, your first notice is a wet feeling). I am an engineer with expertise in product design, machine design and fluid mechanics. I do expert consulting in these fields and teach these topics in one of the top 5 engineering schools. The engineers that designed this product (unless my lid is missing a check valve) did not properly design this vent. I took this lid, flipped it upside down and filled it the fluid I was using, and the lid leaked. It takes little pressure to move fluid through it, especially if there is a surfactant in use. I suspect they did not consider how the fluid would interact with the geometry + area of the vent if the fluid in use wasn't the same viscosity and/or surface tension of water. If the tank is tilted a little, or say it falls over (as is reasonable to have happen to anyone in normal use) then chemicals will leak out. A very simple, low-cost check valve should have been used to prevent users from getting doused with chemicals the engineers should have known are exposure hazards. This is a major safety problem that should not have made it out of the engineering prototyping/testing phase. This should have been caught in testing. As it is, I can still use the sprayer, but now I don't feel safe filling it more than half way, so much of the time savings I had earlier experienced is now lost. Greenworks has provided me with great products in the past, but this one will cause me to really look closer at future purchases and/or just switch to other. It really bothers me that people can get exposed to things because of such a simple mistake that should have been identified before product release.

Works well. Battery lasts plenty for 1 acre lot (half acre lawn). Easy to clean and maintain.

I own three other Greenworks tools that use a 40V lithium battery and this item is compatible with them. It was easy to set up and use. I figured it out with minimal help from the directions. I did a test run with pure water and tried all the various spray tips. There was plenty of pressure in the hose. It worked great. Now I got to get to work for real in the yard.

Sprayer is great. Works very well and can get multiple tanks emptied and not even use half the battery. However, my belt buckle broke meaning all of the sprayer weight is now supported on my shoulders, and not my hips. When I contacted Greenworks they said this isn’t a covered part by the warranty. Very disappointing.
