Rated 5 out of 5 by from A Must Have for DIY Lawn Care After firing my lawn care company, I decided to tackle providing my own lawn nutrients. I bought this to apply micronutrients and supplements to my turf. Adding iron can be a messy proposition. This sprayer wand offered great control over the stream and enabled me to keep the solution off the concrete and limestone edging. I have 10000 sq ft of lawn, and the 2 AH battery included was plenty powerful. I also appreciated that once the solution in the tank was running low, and it did not sputter link the pump sprayer I have. The arm strap was comfortable with a full 2 gallons of liquid. I have enjoyed using this product and has made my tasks much simpler.

Rated 5 out of 5 by from Ryobi Chemical sprayer This product is a great buy if your tired of pumping an old sprayer. It has great quality and long stream of spray to be used with lawn and garden sprays. A lot of reviews says this product will freeze up and the pump is weak. I have found none of this to be true. Ryobi’s owners manual says you must run soap and water through it after each use. This is to prevent what your spraying to eat up seals and the pump. Overall this is looking like a great product and another to add to my One+ Collection

Rated 5 out of 5 by from Awesome Sprayer Ordered this sprayer in hopes of having an easy spraying experience without the routine pumping of manual sprayers. I was actually blown away by the performance of this sprayer. Able to spray yard, bushes and yard trees, house perimeters without having to stop and making a single pump. Usual spraying of these areas with a manual pump would result in several stops to pressurize the tank again along with the aggravation of stream loss as pressure went down. This Ryobi sprayer maintains a constant pressure that allows continuous spraying without stopping no matter what the jobs is. I will never regret this purchase, it's been a lifesaver already. Although the yard where I live is small, we also own a home 45 minutes away that is over 1/2 acre in yardage along with addition area of the farm we take care of.

Rated 5 out of 5 by from The Kits Worth the extra Money I was just going to buy the standard 2 gallon sprayer to try out, but I decided to spend the extra cash and go for the kit the get the extra features. After using the sprayer, I'm so glad I spent the extra money, it's well worth every penny.

Rated 5 out of 5 by from Interchangeable Tanks! I love that the battery keeps the tank pressurized. The ability to swap out tanks is a great feature! The metal wand is an added plus. If you are looking to use different size sprayers for different jobs just know that the 4 gal wand and spray tips are bigger than the 2 gal wand and nozzle tips so they are not interchangeable. Overall this is a fantastic product!

Rated 2 out of 5 by from Great for a while I bought the P2803A chemical sprayer in the spring. I've used it four or five times now and found it great for weed control, spider control, and spraying cleaning chemicals on our stone entry. Now it no longer maintains pressure. Hit the trigger, it sprays about a second and then dribbles. The worst part is, support is essentially non-existent. I went on line, and it keeps offering me repair centers. I tried chat, and they did the same thing. No suggestions on what might be the problem or how to approach it.
