I found this to be over rated
The product itself works well but it didn't stop my squeaks in my floor, but it did help with some spots on the floor. The video they show online makes it seem like it will work for every squeaky spot, but it didn't. I must have used hundreds of nails in one particular spot thinking this has got to work but it didn't. I think this is a 50 / 50 product in terms of working for a squeaky floor and I will buy again because it did help with a few locations.
