I know everyone has an opinion on their favorite AAA light. I bought 6 of the SL Microlights today. I find them to be nice but the tailcap is a bit hard to push. I guess that could be good so there is no accidental turn on in a pocket. I love my Fenix E05's also. Can anyone tell me about the 4 Sevens Preon 1. I cant find any good reviews on YouTube. I see they make tailcap options? Any help would be great. Thanks, Howard
