Not bad, best with round vitamins.
Working out well so far. Gives you all the room it has possible, even has space up in the cap. Holds about 6-7 round percocet sized pills -oblong shape not so good, seems takes up more room. Easy to put on a key ring and is thick enough that I'm not worried about it falling off and you can tighten it good as well since it has a rubber O ring as a buffer. Havnt put it under water yet but I will ad some pictures when I check it out.
