Gtopin Ultrasonic Pest Repeller

i was very skeptical about this product. i usually dont write reviews but this product worked way above my expecations being that i live by a really big park and surrounded by country area i thought there was no way this thing could keep these pest away although after almost sticking my hand on a black widow that had sneaked in a cabinet in a upstairs office / library area i decided to give little contraption a shot at entering the once bachellor pad to now clean spider less and ant free house and those ants were aggressive sometime i felt they had a spy cam set up and a teleporter they were so fast to create an assembly line on a piece of leftover whatever sitting on a plate from a snack while surfing the net oh those were the days. the days the ants went marching one by one. well dont let the door hit yo on the way out hoo rah hoo rahgreat devise works extremely well thought i would add a little sauce to the spaghetti

Was skeptical if these would really work but I am thrilled to say, I haven't seen an insect in the house since I installed them.

how long to take active ??? i got plus in power outlet after 24 hour with 12 pack in my 1600 sqf home still to see mosquito !!! lie and lie product ...i will return after another 24 hour if still see it !

The product came with very limited instructions and does not address the issue. 2 of the 6 pest repeller when plugged in show a red light, what does that mean? When exchanged with a different repeller in the same plug the red light does not come on so it has to be something with the 2 repellers! Please respond and let me know what the issue is.Thanks, Patricia Burger

Not working for flies, ants and mosquitoes

does not work

Didn't seem to change anything. Business as usual for the pests.

Love these
