Just received the “B”, special sale $39.00 with gas lighter. It’s super cheap feeling, as you would expect. I bought it just to check it out. All the parts were clean, EXCEPT for the inner cap, using 99% ISO, the QTips turned GREY, so as always CLEAN any new vape device before using. Doesn’t come with tip orings, in case you wanted to use the tip on another stem. I’ll probably give it away since I own a few premium stems like Revolve and Simrell, which are NOT silicone. Same issue I have with normal “M” stems…. TOO SHORT.
However, the low price would make it a decent recommendation to someone that hasn’t jumped into the DV world because of price. Though they might get frustrated with the only bowl setting of HALF BOWL, guess DV figures that might push new users toward the more expensive tips with adjustable bowls.
Obviously, if you are sensitive to SILICONE, then don’t bother with this model. At the very least, I have one more captive cap, and a cheap lighter I don’t need either.
