Previously I had a treadmill Belkin. It disturbed above all that rain and sweat got me through the neoprene on my IP 5, and the low tolerance for arm diameter. Then I came across Quad Lock and got myself a year ago, the bike set with Poncho. The treadmill is the perfect complement to the set: lock closure clicks bike-set as in a safe and the phone is achievable thanks to good and unobtrusive platziertem unlocking - if necessary - ready to hand; very great latitude in arm circumference, suitable for thin upper arms of ladies size 36, as well as trained upper arms, loose to XXL; no fumbling to force the phone into the neoprene brace, then remove it after training again "with sweat" to. Since me the case of Quad Lock, has preserved in spite of the case on asphalt on a leading edge, in front of a broken display, I use my IP 5 just in case: super fit, very stable, which feel like good to me and it carries much less on than I initially expected. Then I have still gained the 2-piece connector kit: a place in the car and determined 3 times changed the place until I was satisfied. The adhesive backing is the relocation survived loose, could be removed without residue and also holds half a year later still rock solid. Although has no click-lock, but remains securely in the desired position (horizontal or vertical). For the second, I have not found a meaningful place and use it as a substitute. The set for the car I do not think so successful because of the treacherous imprisonment spots on the windshield, which invite to go. So now this recession has become a tour d'horizon through my world of Quad Lock, but I think without the totality of the concept can not properly evaluate the price / performance factor. The products are not cheap, but worth the price for me and I have yet found no better coordinated product range.
