This is not about TubeVN per se, just about the Tubes in general:
I really liked this light when it came out, and got a half-dozen for family and friends.
Six months later, most of them no longer work.
So I just want to say: Tubes die a lot. Charging problems, mostly, I think.
If you buy a TubeVn and it dies? It probably died because it's a Tube, not because of what Vinh did.
There great little lights, and I wish they held up better.
