Borosilicate Carb Cap by VGoodiEZ
Way better than the stock one. Less messy. Great service as always
After seeing all the reviews about the stock cap I got this replacement and it is great.
To echo what others have said, this thing makes my experience with the wand noticeably better, and it doesn't get nasty like the iSpire cap does.
This thing works great - better than the stock iSpire cap actually. It's more heavy duty, more compact, and doesnt immediately shatter into 345,123,234 pieces when you drop it.
