Have had my Cobra for a week and finally got my frosted purple dragon tank today. I ordered the atty first to make sure I would get it before they sold out then ordered the tank after. Sandy delayed my tank. I have to say I like this think even more now. The custom tank looks very very cool on there.
My only issue with the Cobra is the top cap is an incredibly tight fit (5ml version). I really struggle to get it back on. I'm afraid I'm damaging one of the o-rings every time I put it on, it's that tight. It takes a hell of a lot of force to get on there. Anyone else having the same issue?
Did you try lubing the orings before putting the cap on?
