I almost bought a GLV myself, but decided not to add one to my collection as well. Simply due to the fact that if a part went bad, Id be out a unit for an unknown time

I had an issue with the adapter of my prodigy V2 and it was shipped promptly and had my unit working in less than a week. I have had zero issues with all my other mods so if this kind of shipping delay and lack of spare parts is an issue, well Im good with what I have.
I DID use 420s GLV and thought it worked well..when it worked, but when he opened his package the first thing I noticed was all the wiring/regulater exposed in the top cap. I was very surprised it was not covered up w some delrin or some sort of protection period. That worried me. Second, the protected batts that came with it didnt fit. 420 had o "shove" the batts in and ebded up ruining a battery. Worry #2. If Jay were to cover the wiring and hone/widen the tube a bit, I would see this as a great improvement and then if he proves his ways in handling customer service issues has improved, I may be more open to a purchase. However, after seeing this thread....Im definately wary of GLV period.
