They work great but I wish the description mentioned that you need to dome the screens to have them fit in a wpa however the customer service was very responsive when I contacted them about the screens not fitting
They fit with a little doming of the screen
These screens are too big for the Solo mouthpiece but they fit (somewhat) with some work. They’re cheap though...
These are a little big for the Arizer stems, but work just fine if you're careful. And WAY more affordable than buying from Arizer! Fifty of them for what Arizer charges for four. Deal!
Well made, but too small for the X-MAX v2 Glass Mouthpiece.
