It's a pretty versatile piece, it does have a large volume, but you don't have to draw heavy you can still sip even with a whip, you can load as much water as you want to decrease the volume and increase resistance, the perc purrs smoothly, but yes it takes a lot of draw for a length of time if you do want to milk it up full even with a decent amount of water, it's a great piece for heavy hitting vapes but it does work for smaller portables too, it is versatile. Yes it is large, if that is a concern then take heed, that other piece from DHgate is also a bit large but different with the dewar style downstem and yes the perk, it is more similar to the GooRoo 3piece than the TAG really...
