I love the Cleito EXO and how rock solid it is. I have yet to have one of these tanks leak on me, while providing a great vaping experience. One suggestion I would have is to create a Cleito EXO tank with the top fill design of the Triton 2. Often I have trouble removing the top of the Cleito EXO by hand and I need to grab my Leatherman from hip to get it off for filling. I am not tightening the top after fills or cleaning with any extraordinary force just a gentle hand tighten. I loved the top fill design on the Triton 2 but was having to many leaking issues from the bottom of the tank and switched to the Cleito EXO when it was released. A hybrid of these two designs would be a perfect tank in my humble opinion.
