GB-187-s arrives today. @Ratchett do u find the mp hole too low? Is there any splash back?
I only use my GB-187-S for vaping flowers (never dabs). So I can't comment for dabbing, but for vaporizing, I have zero problem with splashback. Even if I use fresh water and NACE.
I fill mine right to the top of the perc. It's still one of my top 3 favorite glass purchases so far.
Edit, the *ONLY* issue I have with that glass is ABV blowback. Seems to be a bigger issue with this glass than some other pieces I use
