This thing hits like a CHAMP, and doesn't leak a drop. Everything you've read is right. SUPER easy to build on the HUGE deck (just tuck the cotton down into the ports like a dripper, loads of space for big coils, never a dry hit, even with it a bit overstuffed with Japanese cotton, and NO LEAKING...NONE. I've had both the old Griffin 25 and the Griffin Mini 25. Both were ok, but the mini leaked like crazy, and the Griffin 25 was tough to build right, and even then was temperamental. This thing is a dream, great craftsmanship, all threads are nice and smooth, and my god does it hit great. I never knew what I was missing when it comes to flavor until vaping this tank. I'm forever sold on Griffin with this one.
