Let's hope third time's a charm - OpticsPlanet Exclusive Swampfox Sentinel 1x16mm Ultra Compact Micro Red Dot Sight

I ordered the automatic green dot version from Optics Planet. The dot wouldn't change intensity and I couldn't see it in the daytime. I returned it and bought the manual red dot version. Looked much better, but it wouldn't shake to wake. I couldn't make this thing wake up with a stick of dynamite if I tried. So now I'm returning #2 and exchanging it for a replacement.

This is disappointing because I have a number of other Swampfoxes and they all work great. This particular model has been terrible.

I'm hoping that third time's a charm.
