Love the HD 3-piece:
-nice strong thick glass
-perc is in removeable downstem so you can play around with airflow by covering holes or using different downstem
- really great mouthpiece shape. And if it isn't for you, change it out for one you prefer
-Sooo easy to clean. Not a factor to be overlooked. Being able to disassemble and reach everything for a good hand scrub if needed is super.
But do note that it is a tall one.
Great pick up by VGoodiez.
