T3 only recommends using their diffuser with all of the T3 dryers including the Overnight Dryer. While the diffuser does not fit snugly on the travel dryer and may pop off occasionally while blow drying, any other diffuser could not withstand the type of heat released from the T3 dryers, and would actually melt onto your dryer. The T3 Diffusers contain tourmaline, and this is why they work with this type of heat without melting. If any other brand's diffuser is used with the T3 dryers this will nullify your warranty.
