    • Excellent sprayer
Style: Sprayer
I discovered battery operated sprayers last year. I bought a 2 gallon sprayer loved the ease of use. No more stopping to pump it, consistent spray pressure, etc. This spring I discovered 4 gallon battery operated sprayers are available as well. I have a pretty large yard and decided it was time to get a Chapin and I have no regrets. I used it for the first time this past weekend. I sprayed 4 loads and the battery still shows full charge. I love not needing to pump it by hand. Just fill, mix and go! Pros: 1. Wide fill opening makes it easy to add water & other ingredients. 2. Opening has a removable mesh basket to filter the liquids that are being added. And the sprayer has 2 other filters to help ensure no plugged nozzles. 3. Spray pressure is strong and consistent. 4. Very minimal sound when pump is in operation. 5. Sprays out virtually every last drop in the tank. If you are wearing as a back pack, stand up straight or it can't get all the liquid. I noted some complaints that the sprayer won't use all the liquid in the tank but this has not been my experience. Cons: 1. For me this is minor but, the hose could be a bit longer - maybe an additional 1-2 feet. But, in general, the sprayer worked well so this is not a major issue for me. I hope to get many years of use from this sprayer. And it helps encourage me to keep after the weeds, etc. in my yard. I think, in the long run, it will keep my yard looking better because, before, I hated getting out the hand pump sprayer, mixing numerous batches, etc. This is a good sprayer at a good price. ... show more

    • HORRIBLE quality product - I had TWO defective units. DO NOT BUY
Style: Sprayer
The media could not be loaded. This is a story of two defective units. The first one I set up, right out of the box, charged the battery to 100% and added about 2 gallons of water. The pump turned on, but would never prime. Kept it running for 3-4 minutes and never ran water through the pump. Submitted a return/exchange and had the new one on my front door 2 days later. Opened the second one, and got it all set up. Added 2 gallons of water, went outside to test it and the pump primed properly and sprayed perfectly! Went for some test passes to check my walking pace and the back of my jeans was starting to get soaked. Took the pack off to find that the tank was severely leaking (like many of the other reviews on here), tightened the seal ring, and did not fix it. Returning both, going another route.

    • Great backpack sprayer
Style: Sprayer
Was such a great sprayer, I bought another one after 3+ years of use. Kept outside in hot Texas sun, and through historic freeze (even battery). Unit put up with so much more abuse than it should have been subjected to. Do be sure to charge battery every month or so (it's lithium). Would probably last MUCH longer if properly cared for, lol. Only thing was unit has "one" pressure, which is pretty high... can't modulate the flow down. ... show more

    • It's powerful!
Style: Sprayer
This product was super helpful when it came to spraying our yard. We used it to spray our weeds. The spray made it super quick since it was both powerful and had a wide spread of the liquid. It also holds a lot, so it's super convenient since you don't need to go back to refill it. Since it is powerful, it will go through the liquid you put in it very quickly, so you need to be walking and moving the whole time you are pressing spray if you want to not waste any of the liquid. Also, we had trouble with the strap but learned that you need to clip the backpack strap to the metal rods at the bottom of it and NOT the plastic part. ... show more

So I bought this knowing there were complaints about batteries, leaks and just general disappointment. I also knew once I received it, this thing was getting torn down. Here is what I found: the o-ring between the pump and canister had 3 spots of lubricant. I fixed that with Vaseline. The complaint of batteries getting wet from leaks... so many opportunities in there, the o-ring was just the start. Looks like a general purpose cement was applied to the discharge line. It wasn't enough and pulled apart easily. I applied cement to the barb, applied the hose and clamp. The battery compartment has 2 drainage holes, left and right. They are small and will likely plug up quickly. I sealed those and made a single larger hole up front, under the switch... at least I can watch it there. As for the draining batteries, that one is easy to see. This has an on/off switch. It disconnects the battery 100%. Battery draw will be happening before that, at the posts when they get moisture and corrode. I sealed those also. So, Vaseline and a silicone based adhesive, a drill and bit, a touch of general purpose cement and 20 minutes time. If I don't get all the bugs this round, I'll tear it apart again. It was a cheap enough and I know the brand. If it goes well I will update. If it doesn't, I will correct it and update. This is a 3 star fix before you try item. Well, first update. O-ring leaks. Blue rtv gasket maker to the rescue! The good news. The sealant on the battery terminals did its job. ... show more

    • Just plain GREAT SPRAYER!
Style: Sprayer
I own a few of these sprayers, AND I LOVE THEM! They perform exactly as manufacturer claims, spray distance is excellent, battery life is great, overall quality is great (despite some of the less-charitable reviews I've read). I've been buying nothing but Chapin sprayers since the first one I purchased. Why look for something "cheaper"?? Sounds cliche', I know, but sadly, "ya' get what ya' pay for" (usually, some rare exceptions to be fair). ... show more
