Pumpless Battery Powered Sprayer, Translucent

Works great. Don't have to stop and pump it up. Very easy on/off control. If fact we now have 2. I bought the first to do my own extermination. Then my wife saw how well and easy it works, she got one to spray her flowers and plants.Highly recommend.

Works beautifully. Much easier to use than an ordinary pump-up sprayer and is more effective. Wish I had this years ago...

The star ratings I gave the product overall and in value are reduced because I haven't used the sprayer enough to know about longevity. The star rating for ease of use would have been 5 if not for the problem described below. Because of this issue, I must stop and get my glasses to decode the symbols provided -- it REALLY shouldn't be this hard. (Note: For the attached photos, I made sure the lighting was just right and the photos are considerably enlarged.)I have had this product for about 6 weeks and have used it twice, each time for about 1-1/2 to 2 hours. It has performed flawlessly so far. I am VERY happy to eliminate the frustrations brought on by the small hand pump sprayers. This sprayer does a much better job of spraying -- with a uniform spray pressure and spray pattern at all times -- than I could ever get from the small hand pump sprayers.Before I bought this, I read through a lot of the reviews on this site. Many of them talked of battery failures.Now that I have my own unit, I have observed how poorly the battery polarity is marked on the battery, the charger, and the carrier the battery is put in to insert the battery into the sprayer. For all rechargeable batteries it is paramount that proper polarity be observed when charging. The (+) end of the battery must be connected to the (+) indicated on the charger. Reversing the polarity will usually destroy the battery.Further, I take extra care to ensure proper polarity when inserting the battery into the carrier that slides into the sprayer. Depending on the circuit design, reversing the polarity in this situation may or may not cause failures. I have done no testing with regards to this circuit -- I just make sure the battery is inserted correctly. One thing that is unusual, the spring on the carrier goes to the (+) end of the battery. For most consumer devices, the spring goes to the (-) end of the battery.I am planning to clearly mark the proper polarity on the battery, the battery charger, and the battery carrier. The markings it comes with are TOTALLY inadequate. I would have expected the manufacturer to be interested in having these markings obvious -- I suspect their warranty expense would be greatly reduced by simply marking the battery, charger, and carrier in a suitable manner.

I bought a Pumpless Flo-Master sprayer several years ago and loved it. That model used 4 D-cell batteries and they would power the sprayer for an entire season of spraying weeds without the need to replace them . . . and we live in Florida so a season is 3/4 of the year. One nifty feature was that the power switch had a reverse position so you could stick the spray nozzle in a container of clean water and run it in reverse. So it would run clean water through the pump making cleanup a snap. After several years of heavy use I realized it was gradually wearing out and that one day it was going to fail so I went online to Amazon last October and ordered a replacement.My original sprayer died today and so I used the new sprayer for the first time today and I'm completely dissatisfied and disenchanted having numerous complaints with the product:1. My immediate observation was that my original sprayer cost under $30. My replacement sprayer bought last October cost $43. Today it sells for over $50!2. No more "Reverse" feature.3. It comes with a 3.7V lithium rechargeable battery. How do the astrophysicist engineers at Flo-Master expect that to produce power comparable to 4 1.5 volt D-Cell batteries?4. Planning to use the sprayer today, I charged the battery yesterday so it had a full charge.And now a brief review of the product's performance:I was initially impressed with the output of the sprayer, but that didn't last long because after about 10 minutes of use, the sprayer simply shut off. I turned the power switch off and back on and the sprayer continued to work again. . . this time for about 5 minutes. This performance continued, each time after restarting it would run for less and less time before shutting off. I was down to 2-3 second intervals and eventually I gave up.While not certain of the problem, I'm suspecting the motor heats up and has a protective cut out circuit so it doesn't burn out but I'm so disgusted with this product and the company that makes it, I had no interest in looking into it furtherThis is a classic example of a company shooting itself in the foot. They reached a level of excellence with a superb product and then compromised and cheaped-out on everything that made it great. Oh, and for that you get to pay twice as much!
