So I was only a GGTS user for one week before I got my Just GG, but thought I would give my thoughts.
I can't really say I like one more than the other.
1.) I do like the new axis post, with it being a more solid construction rather than just the battery on top of the spring (would be great if we are able to replace the existing axis post on the GGTS.)
2.) Although the telescopic look is sweet, nice to have the option of an all solid look (acutally rocking that now with an 18650 battery.)
3.) The new center post is nice in the sense that you don't have to take the cap off to adjust the pin if you switch atties, but the adjustable screw part on the Just GG I need to get the hang of. Is this like the Ithaka adjustable pin that I can unscrew more than needed and when I put the atty on it will adjust itself without hurting anything? If so, that is sweet.
4.) I did like the threaded air flow control on the GGTS. The sleeker look on Just GG looks better, but it seems I had more control over the airflow on GGTS, though I know this is the opposite and I just need to get use to it.
Overall, for
vaping for a little over a year now and just getting into mechs about a week or two ago, really happy I went with the GG mechs. Both are top notch and all I have been using these past two weeks.
