Woo! Got them today fro Vape Toy, and they are way cleaner than the stock glass, it looks like they blow these ones instead of cut the bevel. Just got a new fogger and it looks they have switched to the same method as well. The Vape Toy tank is a little wide on the bottom, so the oring is not tight, it does contact the glass all the way around, but I can see where some wiggling might make it leak a little. A slightly thicker oring would fix that right up. All in all, Vape toy has excellent quality replacement glass for the fogger, and they got here in 6 days, as I placed the order after business hours on the 15th. I am satisfied.
