Well... 5 if you count the 3TM glass heat exchanger insert I guess. The 8RD is a throw back to 2018. The 19DX (see www store) is a bigger Artisan version of the 14DE Factory Made product... so there are a couple of glass heater heavy hitters hitting the www store as you read this. However, there also 2 other designs that manifested themselves as well. The 1MT was resurrected from 2022... the OG 20 mm coil cordless vape and the most impressive 5DT, as it Does This. See YouTube video.
The 5DT is an Ispire Wand powered bad ass! It get's it's roots from the 2014 RBT provisional patent detailing a dozen metal mesh heater designs so we reached into the vault for this one ;) I will give a hint, I see glimses of it in the Dan Morrison Nomad as well as the Tiny Might heater. My reasoning for divuldging the 2014 patent wasnt to protect ideas, but to prove that 10 years later I had the idea and am in no way coping anyone... I am just real slow, but man the quality is just $$$.
Anyway, It's a glass design that imparts just the right level of conduction passively such that this is a No Stir device... and you can put a bit over a half a gram in it sooo... It works well from 550 to 750 degrees on the Wand. You can either hit it on high to warm it up and drop it low to get it from the get go... Or you can just take your time and temp step it. It takes 10 seconds of so of a pre-heat. This is to saturate the heater and surrounding glass and then it is off to the races. Once she is warmed up she can pour out smooth cool vapor at 600 or you can crank it up to 750 and really blow a load up the chimney like no one's business. It has a 19 mm glass fitting and a handle to facilitate clearing the big 19 mm water piece that this screaming eagle requires. The glass is our US standard 19 mm joint that has a US made custom screen in the straight tube section. Every joint is quality checked to ensure that the screens fit tight.
The best news is that the design although highly effective is dead simple... So the cost can be kept low. So, don't snooze on this top secret device that will start to ship against the pre-order (hint) around the end of the first quarter. No need to see her, I will show you what she does... she Does This... the 5DT is blazing into 2024... don't be left on the sidelines for this one.
Video Evidence of Does This coming to a YouTube channel near you soon.
