For the price (about 30 in Pearl) the product is quite useful. Before buying but you should consider the following: - Camera head with 10mm diameter is very thick! - Optimum focussing at max. Distance from 6cm is a strong limitation: you can when looking at the camera in a larger container imports (eg water tank) virtually see nothing, because the walls are too far away. - The software is simple but useful. Stills and videos are easy to customize. - The mirror is unusable.
