This is a nice little product at a very reasonable price. However, since buying it I have upgraded my phone to the HTC one and this casing is about 5mm to small internally to fit the phone. If I had it to had I would provide the internal measurements...so sorry for not being able to be more informative.
I bought this to secure my bikes in the back garden. Wasn't 100% sure what to expect but figured it would do the job. I was therefore very happy when it arrived. It was a lot bigger than I had pictured it. I lot heavier and considerably more sturdy. The fact that it can with appropriate sized drill bits and fixation bolts was wonderful. The only thing that delayed my placement of the strong hold was having to charge my drill. All in all a VERY good bit of kit.
