Happy with the purchase, reads my air rifles fine. Assembly is simple, just match up the logos on the light bars with the ones in the manual. The blue leds will light up when turned on if you have it right. To change from M/s to Fps, just push the button immediately after it says 'on'. It does not seem to remember the setting though and reverts to M/s after powering off.
