This is an extremely well made product, very strong but still a comfortable material. It is a great idea and was hoping it would charge phone and watch together. I wished these had been a perfect fit, I really do. But it also makes up in some nice touches. Seems to be ok. Again, that single, larger driver in the 5 is what works. With this fabric rack, you?re putting MOST of the pressure/load ON THE RACK first, and then you simply tie it down to your car?s roof. 5 and unfortunately it did not fit my feet nicely. This book is awesome! Very good stand.
