Works very well, I read the reviews and was still skeptical but I have to be honest this stuff is amazing. I ordered it last night about 1:00 am and it arrived 2 days later, I arrived home from work at 11:30 pm and couldn't wait to use it. By the next morning I saw nothing moving and was really surprised. I am ordering another set of 4 just to have in case. This stuff works so well I am going to have it ordered at work to use.
