Effective
I've tried many different repellers and this one works best, lasts longer and has more frequency variables to deter a variety of pests .... After years of running one down in my basement, I heard some scratching in a wall this fall.... I went downstairs, repositioned the repeller towards the noise, set it for rodents and they disappeared... The trick is to switch it up occasionally...change frequencies and reposition or the pests become innured...
This is my 3rd unit and I've brought it to Switzerland and found a 12v charger that has the same plug... The squirrels disappeared overnight in my studio...well made, I've had them running off and on for years without a hiccup... I even ran one outside one winter (under cover) to deter squirrels...
