Six-pack arrived on time and in perfect condition. Very easy to install  plug in and turn switch on. We had a critter or critters loudly scratching in family room wall. Directions in package do warn that there could be increased activity right after installing the repeller. Fingers crossed that we have avoided an expensive exterminator call.

This is a great tool for extending the amount of things you need plugged in that aren't heavily needed to be identified by the pc. It wobbles a bit, not exactly too stable or stern, but it works!

Hoont Indoor Plug-in Ultrasonic Pest Repeller with Night Light - Pack of 4 - Eliminate All Types of Insects and Rodents
this is a nice set of 4 as you can put them through out your whole house and not have to worry about using pesticides. I got these for ants and they seem to be working well. the night light adds a benefit as well. so far so good. I will update my review as summer time really kicks in to let you know how well they work then. got these for free for my opinion

Units seem well made. Red LEDs are surprisingly bright. The on/off sequence is mostly more rapid than I expected, for whatever that's worth. There is no way a pest animal could miss seeing the flashing pair of eyes at night, and at a considerable distance. So, if the concept is effective, this unit will be very effective. I have only sporadic, infrequent visits from coons and skunks, so may have trouble determining their effectiveness. Time will tell. But they are reasonably enough priced to give them a try.

It works as advertised; no complaints.  It help me to plug in lots of wallwarts into a conventional power stip.

So far, it has been over one month, the mouse blocker has worked great. I did do a couple of additional things to hopefully keep the mouse out like park outside instead of the garage (this is where the mice were constantly getting in my car) and I had my mechanic put up a mess cover underneath the firewall in my car.  So all is probably working together to eliminate those nasty pests!

Good tool for getting the heads plumbed up.

Works fine, but a lot of excess movement can cause the plugs to loosen/unscrew themselves. No problems at all if hooked up and left alone.

Some places require plugs to stay close to the wall instead of sticking in perpendicularly.  This plug does the job!

It's simple. It works. It'll allow me to rotate a grounded plug at the socket. Problem solved.

Works well. We will see how long the auto retract continues working.

We have a new, larger deck on the back of the house and I have added a number of bird feeders.  We get a very large number of birds visiting the feeders, which I like.  Recently, however, a raccoon has been coming onto the deck and raiding all of the bird food, eating at least 10 lbs a night.  A bit dubious, I ordered this product to see if it would work.

The first one I got seemed to do nothing, so I obtained a replacement from Amazon.  Fortunately, the second one worked and -- so far at least -- my raccoon problem has gone away.  The device is quite simple; it stores energy from sunlight during the day and then continuously flashes a red LED at night.  As odd as it seems, it appears to work in my case, and I'm quite happy about that.  Raccoons are really tough to keep away, and this product seems to do the trick.

UPDATE AFTER TWO WEEKS OF USE:

This really does the trick.  I've not had a single raccoon problem since setting up the replacement.  Remarkable!  I changed my rating to five stars since this really works and the initial defective product was quickly replaced at no charge by Amazon.

Hello,
I have a Koi pond in the back yard that was always being visited by raccoons. After I became fed up with them not paying me for the fish I decided it was time to get a electric fence around the perimeter of my property ( land mines were out of stock here :) The only problem is that I wanted to make sure that the fence was working. Sometimes they will get shorted out when they are strung a long ways and so I would reach up and touch the 3-4k volt line. The problem was that sometimes I would soil myself in the process and that is where this little gadget came into play. Now, I no longer shock myself and go through the embarassment of soilization. Get it. It works every time I use it and it won't cost you an arm or a leg!
