I have a LT clone, like this one
Vari-Tube 18650 APV I paid $40 OTD in a brick and mortar, it works well, but that's about as good as it gets! It's cheap! The bottom cap, I'm just waiting for the spring to push it out! Had it a bit over a week and the chrome is wearing off the fire button already. The threads are loose as a goose, even tightened down I can wobble my tank side to side. Every time it slips out of my pocket I fear it will be the last time it worked if it hits the ground! And it's long! Really long! 1 3/4's the length of my BB.
For entry into VV, it was great, cheap and easily available. Do I wish I'd spent more, sure! But I'm just getting back into it, this made the transition a lot easier as I can adjust the volts through out the day to suit what I need.
Do I want something better? Absolutely! I wish I had the money for a Provari, but I don't right now, and may not have for a VERY long time! I'm looking for something in between, but it has to be durable to meet my lifestyle, there lies my rub! I can beat the snot out of my BB and it just doesn't care! The LT clone, well if it makes it two more months with me I'll be very surprised!
I looked at the Zmax in SS, but really, by the time all is said and done it's about a $40 difference in price, I'll save up the $40! I've been looking and looking for something other than these two choices. I even looked at a Bolt with a Kick, but by the time you buy the Bolt, the Kick and two extensions you are at the price of the Zmax SS so why bother?
I feel the pain, I assure you!
