I wonder if this is coming from the same supplier of ADA. I wish someone had both in boxes to compare. Looking really quickly, they have a few other ADA knock off stuff. However, the inline diffuser is not an ADA copy.
That said, I don't know if I am excited about this or not. One one side, I feel like cheap alternatives are great. On the other, I don't like how they are going after ADA's exact products and using the same branding colors as well.
