Quick review of the Both the 510 only SS Chi You clone compared to 510/Ego SS Chi you clone.
510 only . Threads are good, 510 bit poor wobbly, but both top and bottom adjustments are great, heavy beast thick SS, non-reverse lock is pain. Great finish tho and vapes well with cartos and 510 tanks. Also fine with ego adapter. Narrow tube inside so some 18650 efests don't fit others do.
510/Ego Thread all around feel rough, but thinner tube so lighter and takes both efest 18650 widths as discussed for 510. I got two units, and 1 ego connector thread is fine but the 2nd is tight and I can't screw a T3 on it but can a CE5. Reverse thread bottom is fine but no obvious adjustment, top has no adjustment for the center pin either.
The 510/ego bottom is not flush with its tube so there is a step in the cylinder.
Useful to note all parts appear interchangable between Chi you's. I have had the Ego top on the 510 bottom and also the reverse threaded 510/ego bottom on the 510 only top.
