Built to last...,quality, looks....this thing is awsome!
None really, hard to find.
This is an awsome drop, I'd say the best one I have ever used. It will fit almost any tank. It also doesn't have sharp edges to cut myself on like the flame drops. I have used alot of drops, but this one is by far the best. And the best part I got mine for $42 with and On & Off. And with this On & off I don't need a bottle o-ring. I don't know what else to say but Go and BUY IT BUY IT BUY IT. Well at least try it.
Hands down best drop! Amazing balance too. Marker feels very tight. Customer Service is excellet as well, very well rounded company.
