Rated 5 out of 5 by from Love this sprayer I've had Ryobi tools for many years and have never had any problems with any of them. When I was shopping for a new sprayer, I fortunately came across this sprayer. I had several Ryobi batteries already, but for $20 more dollars, I opted for the one that came with a battery. This sprayer is easy to fill, spray, adjust and flush out at the end of using chemicals. No more pumping. The wand and nozzle is high quality metal, not some cheap plastic. Uses very little of the battery per spray. Only small complaint is the tank is only 1 gallon, so you have to refill several times if treating a large area. No big deal. I highly recommend this sprayer to anyone.

Rated 5 out of 5 by from Great Applicator When I purchased the chemical sprayer I did not have high hopes, I did however like the idea of not having to stop spraying constantly to pump up my old sprayer. This tool was a blessing in disguise, not only do I no longer have to stop and pump, I now have even distribution of the fertilizers I use for my garden. The old pump sprayer would work good for a minute and then the spray would become inconsistent as the pressure dropped. This little beast allowed me to keep spraying and focus more on completing the job at hand and making sure that all of my plants received good coverage. I would recommend it to anyone who using a pump style sprayer.

Rated 3 out of 5 by from Decent Sprayer with Two Issues One of the appeals of this sprayer was the measuring cup/cap that comes with it. Unfortunately and unbelievably, the measuring cup is marked incorrectly! One tablespoon=.5 fluid ounces, so two tablespoons=1 fluid ounce. Unfortunately, two tablespoons of water poured into the measuring cup only come up as .5 fluid ounces using the markings molded into the cup. Inexcusable! Secondly, the battery fit into the tool is way too tight, making it difficult to install and to remove. I realize a tight fit is good, but this is overkill. Overall, the sprayer performed well the one and only time I have used it, having received it just this past week.

Rated 5 out of 5 by from Better than expected! Bought this to make spraying weed killer alongthe fence of our 1 acre lot. I was concerned that the battery would not last long enough to complete the job, those concerns were laid to rest after the first use! I refilled the tank 3 times and had juice to spare after I was done spraying! This made this chore so much easier and faster to complete! Glad I purchased this and added it to my collection of GREAT Ryobi tools! Love that Ryobi took the initiative to make multiple tools that take the same battery! Others are now copying Ryobi but I'll remain faithful to Ryobi. I haven't purchased a bad tool yet with the Ryobi name on it!

Rated 4 out of 5 by from Great Product! I have had a flea infestation in my home... after struggling with several types of pump up bottle sprayers... I came upon this at Home Depot... what a Godsend!! No more pumping every two minutes... which is time consuming and tiring... this wonderful device makes it easy to spray the interior and exterior of your home in no time flat! One tiny criticism... the nozzle could be better designed to give more control over the spray pattern... all the control from a stream to a mist happens in the last fraction of a turn of the nozzle. It means you may well end up using more chemical than you actually need to... never-the-less... this is an awesome product!!

Rated 5 out of 5 by from Great Sprayer Overall this is a good sprayer especially with the large battery and longer power. But there are a few design features. The on/off switch needs to be on the handle like for a "thumb" on/off. Where the switch is now, you have to put the sprayer down ow use your other hand, (usually holding the wand), to shut-off the unit Which brings me to the second problem. The plastic nuts to tighten the hose connections do not fully tighten or go all the way while threading the hose connections. Because the hose connections do not fully tighten, when you release the wand to shut-off spray, the p[reassure builds up in the hose and the connection leak at the wand and the unit tank.

Rated 5 out of 5 by from No design flaws Easy to clean, battery lasts a long time over multiple sprays, pump has good pressure, the on/off button can be controlled using the hand that holds the sprayer, the feed tube almost touches the bottom of the tank so that there is very little wasted chemicals at the end of the gallon spray, the lock feature on the sprayer is good to use, it is very quiet, the gallon tank has volume marks on the side, and the filler cap can be used to measure in chemicals. It is ideal for occasional use and is much easier to use than a hand pump version. The wand is metal and the device comes even with a set of spare seals for critical components!

Rated 1 out of 5 by from Poor spraying power I had high hopes but found this sprayer to have half the spraying pressure and distance than the $10 pump sprayers I've always used. I have plenty of battery operated Ryobi products, and have also recently purchased a 5500 watt Ryobi gasoline powered generator, all of which I'm very happy with. Unfortunately, this sprayer just doesn't have the gusto I hoped for. If Ryobi comes up with a better sprayer, I'll be happy to give it a try. Meanwhile, I'll be returning this to my local store tomorrow, and I'm back to my pump sprayers.
