I like it overall, but think they might have done better in a couple of areas:
1) the field-of-view feels tight
2) the display is just 800x800, so you get a poorer image in the scope than on recordings
3) I can't see a way to change the appearance of the secondary aiming mark (green diagonal cross)
4) audio recording is recoil-activated not sound-activated, so won't work on a PCP
5) menu navigation is a bit counterintuitive/inconsistent: you have to wind the turret anticlockwise to go down the menu items, but clockwise to increase the values within an item. (Or maybe that's normal... In any case, I keep doing it wrong!)
