Since I was mentioned, my opinion on the Ulton Tripod is that it is very good, but I can't compare it with the original. Can't say I'm a huge fan of the way the deck and top filling cap are removed, lining up those dots without my glasses is annoying, but it's serviceable. Flavour is excellent but not the best in that department when compared with others I own which I feel outclass it, especially when vaping tobacco liquids. Doesn't have the best throat hit for me either which is another downside. Only major issue for me is the 2ml capacity, but it makes a good RTA for when I'm out and about.
Prefer the GT III, GTR and FEV, but the Tripod is in rotation.
