I have to agree with the comment trikky makes in this review of a RooR Standard Non-Diffused Downstem, for the price of a RooR, you should get a diffuser.

Make/Model: RooR Standard Non-Diffused Downstem
Joint Size: 18.8mm to 18.8mm
Craftsmanship Rating: A-
Functionality Rating: D
Comments: The standard non-diffused is the least effective downstem at cooling smoke. Though the RooR downstem is crafted well, it does little in the way of cooling smoke.
It is simply a hollow tunnel to draw the smoke through. For the price of a RooR tube, a diffused downstem should be standard. –trikky
Definitely the worst of the 3 downstems you reviewed so far. The bubble in the pic look decent but I know from experience that these suck. –Chubbs




I also agree, for the price, it should come standard.
Not much else to say.
Nice review.
Still love the way the slit ones look…
Hopefully RooR will wise up and start including diffused downstems with their bongs.
on 4/20 i bought a ROOR and it came with a diffused downstem..standard
From where ? a site or local shop ?
i haven’t seen any on-line yet that comes standard.
