This product is great. I have used it mountain biking and climbing some 14ers in colorado. The quality is great. At the top of some 14ers the focus is great close and then when you look out is not distorted at great distances either. The only thing I would say needs to be thought about improving is the remote. I think that it is just to unreliable. you hit the button to start it and if you are unable to hear the beep you are worried it is not on. I started with it on my back in a backpack and have since only used it in a front pocket for easier access to make sure that it is on. Small inconvenience on such a great device. Would definetly recomment to anyone.
