Hoont Cobra Animal Repeller | Outdoor Solar-Powered Motion-Activated Water Blaster with Powerful Jet Spray for Yard, Lawn & Garden | Scare Away Deer, Rabbits, Squirrels, Birds & Other Animals & Pests

Great for keeping critters away

I used to scoff at the review where people would say, "Stopped working after two weeks," but not any more. Bought this to chase the birds off the newly planted lawn. First off, it says it will detect birds, but unless you have condors landing on your grass, this thing won't scare anything. Pigeons might set it off, if you're lucky. Even large flocks of them. Came out one day to find a carpet of pigeons gorging themselves on my seed right in front of this sprinkler and didn't go off until I chased them off. Then suddenly it was like, "Hey dude, I had this. I was just waiting for the right moment." After two weeks of use, it stopped working. Wouldn't run when it was supposed to. Then, it started running without any movement. Over and Over 5 seconds at a time. Then, it started running for more than 5 seconds at a time. The final straw was when I came home one day to find it had been running non stop for hours. Flooded my backyard hardcore and drowned the newly planted rye and ballooned my water bill. Complete garbage. Thankfully, I'm within the 30 return period, so I will be taking advantage of that and get my $40 back.

Having frequent visits by deer to our backyard was never an issue (actually it was a pleasure to watch them!) until we installed new landscaping. It became a problem as we saw the tender new growth of our new plants being nibbled away nightly.While searching for a solution, I looked at a number of popular deer deterrents and even tried a few that proved ineffective or too smelly to continue using. After all, we added new landscaping so that we could enjoy the backyard, but the odor from some of the popular deer deterrents worked more as a human deterrent!Then I found the Hoont sprinkler solution. What a terrific idea! I ordered 3 units to serve as a "water fence" between the open lot behind us and our backyard. And since installing them 2 weeks ago, we have not seen the first deer enter our planting bed. And there has been no evidence of additional damage to the new plants. So far, the system seems to be working perfectly.As those who are looking for deer deterrents understand, deer are very adaptable and clever where food is concerned. Time will tell if they figure out a way around the sprinklers, but for now they are staying away.The units were very easy to assemble and install. I plumbed them in sequence using 1/2" landscape tubing. It took a little searching to find the correct hose fittings, but once installed, they do not leak at all.I am so glad to have found a humane and simple solution to our deer problems. They even provide a bit of entertainment when our cat inadvertently wanders within sensor range.I highly recommend this product!

I used to own two dogs... past tense, as both have moved on to the Rainbow Bridge within the last year. Imagine my surprise when I found more piles of poop in the back yard after their passing! So I bought this motion-activated sprayer to combat the mystery critter. It took a couple weeks--the critter got smart and moved to a different location--but in the end (knock on wood) the sprayer triumphed over the critter. It has been three weeks now since I've seen any poop, and I haven't had the sprayer set up for the last two of those.You can't tell from the photos, but the solar panel position is adjustable (horizontally). That was a pleasant surprise, as the peak sunlight was to the southwest of the unit where I had it set up.On the bad side, the instructions included with the sprayer are minimal, and not 100% complete (and tiny!); but I managed to figure things out, so at least the set-up & operation are intuitive.They also kind of messed up the hose connection. If you look closely at the photos, the connection at the base of the main unit (where the extension goes into it) is done correctly; i.e. there's a female coupler that screws onto the male threads of the extension. But if you look at where the hose connects, there is no such coupler. In order to screw the hose into the stake you have to twist the entire unit around the hose connector. So every time you need to use the hose for something other than the sprayer, you have to pull the sprayer out of the ground to unscrew the hose.You'll also notice on the opposite side of the hose connection there is another covered connector. There is no indication what this is used for (again, due to minimal instructions), but I assume this is so you can string multiple units together; i.e. it is an output port that you can screw a leader hose into and connect the other end to the input of a second unit. Just a guess... and a nice feature if I'm correct, though I'd prefer to have the output at the side of the unit rather than the front.This next criticism isn't really the unit's fault, but it will be best if you connect a solid hose from the water source to the unit. Don't use a flex hose if you can help it. The flex hose expands and builds up pressure, but when the motion-activated sensor goes off and the valve opens, the pressure in the flex hose drops and the sprinkler head doesn't arc like it should and ends up spraying in one direction. It doesn't make sense, but I've seen it with my own eyes.Lastly, be careful how you set the sensitivity and where you point the sensor. On a windy day, the trees blowing in the wind will set off the sprayer repeatedly. On a rainy day, the raindrops falling down will set it off. The motion sensor is triggered by more than just animal movement.And for God's sake, make sure your wife knows you put up a motion-activated sprayer before she decides to do any gardening in the back yard! ;-) The sprayer doesn't differentiate between friends and foes. By the way, another reason not to use a flex hose is because even if you turn off the water at the hose bib, there's still pressure built up in the flex hose and it'll continue to spray a few more times if the sensor goes off.Overall, though, I'm happy with the purchase. I wasn't sure this thing would work, but I can't argue with the results. There are some inconveniences, for sure (hence the 4-star rating), but there isn't anything that can't be lived with. Overall a nice solid unit.

It works perfectly. However, after about 6 months, I was going to work one morning and saw water running down my driveway...all the way from the back yard. The fixture on the device broke or something and it was gushing water...probably all night. So it didn't last as long as I would have liked, but it drove away every animal that walked through my backyard. Cats, Rabbits, Skunks, Possum, Fox, squirrels. Although...squirrels are pretty dumb and tend to get sprayed in the face for a few seconds before they decide to run away.
