Specific use case - Meprolight M21 1x30mm Reflex Red Dot Sight and Fubs Self-Illuminated Flip Backup Sight

The irons sights are no more usable in the night than in the day. The main optic does work as intended, but is not usable when aiming into a brighter area like from inside to outside. The reticle gets completely washed out. The optic is sturdy and built well but falls in a niche category that wasn't for me. Another thing about the reticle itself, I got the X reticle and it was stupid tiny. I was expecting a larger reticle for the X.
