I've only had my Pyrex RSST for a couple weeks, but I love it. I actually got it to replace my PT2 as my glass tank for the tank cracking juices I enjoy. My first build was using PBusardo's video and came out fine. Lots of flavor using a 50/50 Freckled Lemonade from MBV. Then I saw Rip Tripper's video where he used the hollow wick and I decided to break it down and build the hollow wick. It also works great! The ss mesh gives the best flavor I've had, even compared to my KFL+.
The first thing I did was drill my airhole to 6/64. I think this is a necessary step as the draw was a bit tight with the stock 1mm hole.
I built mine's to 1.6 ohm to use on the Provari.
One thing my B&M told me about the rsst was to be really careful with the tank. It does chip fairly easily and if it does chip, it will need to be replaced as it will leak.
