ok, I gotta ask... if the quality is that good, why do you need so many within 6 months? is it for different colors or what?
1) REOs are a rather *iconic* design. The art student in me just loves them. There are so many color combos too
2) There are many different models......wood and metal and then reo mini (14500), reo mini 2.0 (18490), reo mini 2.1 (18490 plus larger atty cup size to accommodate every rba made practically), reo grand (18650) and then variable voltage reos both metal and wood (VV REOS, take 2 18350 batts).
3) I like to keep atties on one in one flavor, cartos on the other in antoher flavor.
