Solid built product. Fits easily on the bike. Put on the Brake reservoir - Feels solid. Only reason for 4 stars instead of 5 is the phone holder does not expand far enough for Samsung 7 or iPhone 7 plus if there is a protective case. I has to squeeze it in. It fits but had to use more force than I would have liked. If you have a phone that is not as large as these I would highly recommend this product.
