I've retired both of mine (30mm & 25mm) to the dust bin, tired of the leaking.
For the 25mm the Boreas and for the 30mm the Modfather. Both of them are lightyears better than the VCMT. Plus easy to wick and no leaks at all.

Send your VCMT's to me! I'll make you a bunch of DIY juice, lol. Pm me if your interested.
