I bought this because I thought it would be well designed and of good build quality. But it is not.The clamps that hold the phone are poorly designed. The 'v' on each grip that is meant to accommodate the phone is too small - well, too small for my iphone plus - and the strength of the springs far too great than is required for purpose, resulting in the phone repeatedly popping out mid-call. My partner's phone (a Huawei) had the same problem.A fix of sorts can be had by pulling off the rubber pad that presses against the back of the phone when in situ. This gives more room for the phone to sit. I was surprised that this pad was merely glued on rather than fixed i a more secure way.Not only are the gripping springs ridiculously hard to pull when attempting to secure the phone, the 'click' at the portrait or landscape position is imprecise and allows for movement, whereas it should be a definite 'click'. I am used to an SP phone mount for my bike, from which Sandberg could and should learn much.When a phone is mounted, the base is neither heavy nor wide enough to provide a secure footing. I have had to put heavy weights on opposing sides of the thin plastic base plate to stop movement.Having said all this, the camera works very well, as intended, following movement exactly as one would hope and expect.Nevertheless, the design and build quality are below reasonable expectations, and the functional deficiencies mean that I cannot commend this product.
