You have to look at the vape at the time it is introduced..............................I seem to remember the Iolite was the best available at the time. (At least, that's what the cool kids used.)
A friends' Iolite was the first I tried, and he still has great faith although he mostly combusts.
He even thinks there's something wrong with my vapes and that they are not true vapes as they have vapor that is quite visible!
Of course if he filled the Iolite more he might get more visible vapor.
One of the worst vapes I had was a Chinese clone of a Davinci walkie talkie,
It tasted of melted die cast toys and it smelled of burning 80's rubber material.
The faultiest vape I've owned was Puffit 2, I bought the Mighty straight after as it was rumored to be reliable and that hasn't stopped in two years.
I don't like the design and function of Vapcaps too much.
And I think Arizers material choices could've been better when they made my Solo.
It's interesting how some here dislike the Crafty and love Vapcaps, and I like Mighty and have trouble with Vapcap! And there are those that like, and dislike both.
