DC has an excellent reputation in the industry and they come with a 5 year warranty. I turned my video camera on and placed the phone inside to see if there was actually any light given off. and when i scan, i scan from the printer direct to the computer and then go back to the computer and organize all the scanned docs. As it arrives I think it is not that safe on some vehicles as the bottom latch does not attach that firmly even on cars that are on the "Compatible" list. Item does fit big i would recommend going 1/2 size less than your normal size. I don?t even tie the laces - just leave them dangling in the shoe and slide the ol footsies in. Cheap material. smell, soap, bottle, everything. These are oddly shaped for my feet. Highly recommend and I believe these also carry a lifetime warranty.
