I have my SS Vamo for about a month. It gets daily use with no issues. I really liked the idea of having options with battery sizes, being able to take it out in 18350 mode and having VV VW in a fairly small package. I did not expect such a solid
device for the price nor did I expect to order a second one, why do I need another one........IDK but I did lol. IMO anyone wanting to get into VW tube type mod Vamo is the one to get but I do recommend SS.
