I got the BUB from Puffco about a month ago, and I have to say it's pretty awesome - and equally pricey.
$100 seems pretty steep, and it is, unless you went into the Proxy game with the intention to throw a lot of money after add-ons.
However, this piece is extremely well-designed and a serious improvement to the vape quality compared to the stock piece.
Water filtration quality 6/10 - Not great nor bad, but I would say near optimal for a piece this size.
Glass quality 10/10 - Sturdy without being cumbersome, I don't think this can be balanced much better.
Portability 8/10 - The box it comes in is great for transporting the BUB with Proxy and 2-3 jars of extract but it's cardboard and foam, and rather square and bulky - a well-designed case would be very welcome, and I'd gladly throw another hundo after that
A cap/plug set that would make it portable with water inside would be killer.
Looks 10/10 - I actually don't mind using this piece in public, it doesn't look bong-like at all. I'd like to see more compact and discreet looking glass on the market.
Cleaning 9/10 - Really easy to clean, some hard to reach places but if cleaned regularly it's sufficient to rinse well with hot water and the occasional ISO shake.
Price 4/10 - High price is expected from Puffco and for any well-designed piece, but this is over the top, $70-80 would be more reasonable. I could buy 3 Proxyclers for the price of the BUB, I would never use the Proxycler in public though.
If you only use the Proxy at home, you're way better off getting the Proxycler or an adapter and a $50 rig. It's a much better wet vaping experience than the BUB.
With this, I can bring wet dabbing with me when on the go, traveling, social gatherings, camping in the woods, and on business trips staying at dull hotels - and that's well worth $100 to me
