More pros than cons - OpticsPlanet Exclusive Swampfox Sentinel 1x16mm Ultra Compact Micro Red Dot Sight

I've mounted the Sentinel green dot onto the Springfield Hellcat and have run it through 500 rounds thus far with minimal complaints. For the price of this optic, I'm not sure it can be beat. The green dot is PLENTY bright. Thus far, I have found setting 7 out of the 10 to be more than enough on a bright, sunny day. The only complaints I have are minimal. First, there are no audible nor palpable indications when making adjustments, only a silent and smooth twist. Secondly, and this one should have been apparent for me before purchasing; with the manual model and being a right-handed appendix carrier, the "downward" button is located on the right side of the optic, which rests very closely to my pant-line. With the button in this location, I do occasionally find that the optic has been turned off during repeated kneeling and bending throughout the day. Not a deal-breaker but something worth considering and making plans for. Overall, I do not regret this purchase and would certainly recommend this optic.
