In April 2010 purchased $300.00 of Riddex Plus with a 2 years warranty, within the last six month I have killed 6 mice and set out 4 aerosol cannisters to kill roaches, I have also brought 4 cans of Raid Ant and Roach Spray and use each night to kill the critters that come out during dinner or just sitting around watching TV. To my knowledge this represents false advertising from your company. I gave Riddex units to a friend of mine and it didn't work for her either. I will not purchase items of this sort any more from your company. read full review »
