Rated 5 out of 5 by from RYOBI Has Done It Again! Purchased & used yesterday. Surpassed my expectations. A breeze to use & clean. Customer Support (Alicia from S.C.) was most helpful in registering the unit for me. A pleasure to deal with! Highly Recommend. *****

Rated 5 out of 5 by from Lightweight and compact ... no more pumping! I opted for the smaller sprayer unit over the 4-gallon backpack model so my wife could use it more easily. She loves it! The smaller capacity is definitely offset by ease of filling ... just keep a pre-mixed supply of your chemicals nearby for quick refills. Great product.

Rated 3 out of 5 by from Could be better I bought these because the 4gal sprayer tank were too big for the job i do and sprayed too much. Pros: -These spray just right and doesn't soak everything in its path. -The hose and nozzle are much better quality than the 4gal version -Due to the amount of solution that it sprays, you can spray a large area with just one gal. -Battery last a long time. Cons: -Low quality; I use these 3-4 times a week during 6 hour shifts. The button stops working. -Watch out during winter, the nozzle burst open one of the cold nights due to water inside the hose. -Does not come with a strap like the 2gal version. -Hooks where the strap goes is plastic and breaks easily. The reason for 3 stars is because of the built quality. I've had to replace 2 of these already withing the last 6 months. The button stops working properly. It stops sticking. The other issue is that these do not come with straps like the 2gal ones do and the hooks where you attach the straps is really weak and break easily.

Rated 5 out of 5 by from Adjustable Fan Spray to Stream was Great After trying for hours to spray/kill grass for a new driveway with hand sprayers, I purchased this and knocked out the job quickly with good coverage using the adjustable spray nozzle. What a relief for my worn out hands! Just lock it on and no reason to constantly squeeze a trigger. If I needed to do large areas more often I would get the 2 gallon tank, because I had to refill the sprayer often. The weight of the two gallon might have been an issue for me, however. In the future, this size will be great for spot weed treating, vegetable garden pesticide spray and other chores. I measured using the chemical bottle cap, not the tank cap, so I had no issues with the measuring cap dripping. Cleaning the unit by running clear water through the unit and spray wand a few times was a breeze. I couldn't be more pleased right now!

Rated 5 out of 5 by from no pumping I needed to spray more than usual in the crawl space and did not want to stop and pump the sprayer .The Ryobi battery powered sprayer worked great and the battery lasted longer than I did.
