Hi Fc, I bought one of the first batch of Ascents, I received my water adapter as a gift with purchase. It arrived with a very small hairline crack in the part that slides into the Ascent. I was sent a second one as a replacement, so i now have two, One brand new, and one new with a small hairline crack(still totally functioning.) I returned my Ascent and now have these Im asking $40+shipping for both, I am also open to trade for a PVHES GONG stem for the solo, any of the solo gong stems(not just the high efficiency). PM me with any questions thanks! Papal for the $40+shipping Here is the small hairline crack in one of the adapters, it is still functioning fine, however i feel this will be where it would break if it does.. but i could be wrong. Locking thread. no longer trying to sell, trade only ,will make new add for just the flawless adapter.
