... The mumbi cross case for the Samsung Galaxy S4 has maintained with daily use, then was on the belt clip "leather" by. I was first surprised how well looked cross the bag and felt. I had my Wave 2 the "MTT cross bag" which cost well twice. The held for almost 2 years and was processed valent. But what I like better on the mumbi cross bag, is the protected corners (1 *), which is not so in the MTT. Next also the closure with two flat magnets is better than that of the MTT (2 *). However, the two positive points can not consolation over a brief period of use. The sharp metal on the belt clip rubs the material through quickly. Since I could possibly damage my Gütel upon further use, I will not continue using it. In addition, the metal is sharp and could cause injury.
Had the mumbi cross bag held a year, I would buy them for almost 10 again. So I have to look for alternatives me unfortunately.
