I’m very impressed with the quality that Evotech provide. The quad lock system is very easy to install with simple instructions provided. One issue I encountered was when **** in the small Allen bolt to the main phone holder, stripped a few threads and this wasn’t from over tightening. I ended up removing the washer to give me a couple of unworn threads to catch. So, best to nip ever so slightly when **** these in. Overall though, I’m very happy and it seems to be the best position to place my phone when riding.
