Bell + Howell Ultrasonic Pest Repeller Home Kit (Pack of 3), Ultrasonic Pest Repeller, Pest Repellent for Home, Bedroom, Office, Kitchen, Warehouse, Hotel, Safe for Human and Pet

Item arrived on time. Since it was ordered in the UK I expected it to be designed for the UK. But devices have a two prong system which indicates for 120 volt. The British plug system is a 3 prong plug and 240 volt.I have returned it.

Plugged these in with high hopes. Red light flashed slowly on all units which according to the instructions indicates that they are active. Went to check the units on day 3 and none of the lights are flashing. Tried different sockets, etc. but no indicator lights functioning on any of the 3 units. Massively disappointed and a total waste of money.

Wastage of money. Cockroaches were away for a few days. They are back now.

They are seeming like they are starting to work. I put my in maybe a month ago, and I didn't start working anywhere from 2-4 weeks. So be patient with them! They might not work though if your house isn't clean. They go by sound waves, and when your house is a mess, then it could bounce of those objects causing them not to work. I put 1 in every single room, 2 if the room is bigger like my bedroom & living room. Also make sure your not putting them behind anything such as furniture and other soild objects because then the sound wave won't be able to project into the house. These aren't something that need to be replaced often, I think I read maybe every 5 or 10 years or something like that. If your in an area that is high in pests, then you may wanna double up I'm each room if you don't notice a difference after 4 weeks. I was pretty skeptical of this product at first, but decided to give it a try. We have spiders as do pretty much every house, stink bugs, boxelder bugs and ants. But after a month, I haven't noticed any of that around anymore. I think it's worth the money in my own opinion. I did give it a 5 star but I do hate the fact that the red light stays blinking all the time, but however, you do get use to it though! But if it weren't for the red light always blinking, then u wouldn't know if the device ever stopped working until the bugs started coming back, which obviously you would want to buy new ones before the bugs start to come back. I hope this helps anyone who is considering buying these.

Simplemente conecte los aparatos a donde había molestas lagartijas y hasta la fecha no he encontrado más rastros de ellos

Tried it for weeks and nothing happened

Desde que lo puse no volví a tener problemas con ratones, con cucarachas no veo que sea tan eficiente pero con que me ayude a alejar a los ratones de casa me basta.
