v0Lume Reviewed by v0Lume on . phx diffusers? Our diffuser for our trinity broke (someone tried to remove the bowl, taking the stem with it, stem naturally falls on tile floor, crack) and I've been having trouble searching for a replacement. It's 18.8mm, and the stem is about 8-10 inches long. Thanks :rastasmoke: Rating: 5
