i bought 2 RIDDEXPLUS for a roach problem. It does not work at all and my small dog hates it . every time he get near it he growls and shakes his head . it seems to be hurting his ears . with all the complaints i have read since buying it it seams the better bussiness group would do some thing about them . they are a fraud and a rip off . i hope this reveiw help people thinking of buying this product and i use the word product jokeing .RIDDEX ***
it is a truly worthlesspeice of junk ,with no usefullness at all
