Couldn't really find a nice spot to properly showcase my new toy, but here it is:
Close up of the screen:
This is the temp sensor inside the tube:
I couldn't really find a good solution for using both LiPos; I managed to insert them both once, but getting them out again is quite a bit of a hassle, so I keep it at one. When doing so, you have to be a bit mindful, as LiPos don't like to be stored full or empty (I start recharging the extra battery when the one inserted gets low and swap them at 11.4V). Swapping one LiPo is easy.
The overall build quality and print is really good. The filament material is thick and sturdy. It's rough (like a tar surface) on top and bottom and glossy on the sides. Soldering and cables look very clean, although there's a bit of hot glue spilled here and there (might be to buffer the electronics from the case, though). The buttons are *very* nice. The battery case door was a bit stiff at first, but works nicely now. The Slim looks really good in my opinion.
Performancewise the Slim is just excellent. Not only does it heat up quickly (from cold to 180°C → ~6 seconds), but the temps are very *very* consistent. A 180°C session will always feel like a 180°C session and the abv will always look like 180°C (given that the other parameters like grind consistency, pack etc. are the same of course). When done, there's no hue or inconsistent spots in the abv at all.
The hands free operation and the feedback when the DV is ready to draw (light of launch button goes off) is unbelievable comfortable.
Although I'm struggling a bit with the „super hands free“-mode (autocruise or „Deluxe”), which is supposed to reheat the cap when inserting it in the tube without the need to hit the launch button. There's either a timeout or the cap needs to be above a certain temp I believe, but you have to be very quick when using it (extreme back-to-back hitting). It works, but oh boy, that way it slaps you to the moon within a minute. :-)
So I'm using it in the „N“ or „normal“-mode pretty much all the time (you still have to push a button when engaging the heater, but you don't have to keep pushing it down). I'm usually starting at 170°C and finishing at 190°C or 200°C, that usually gives me ~5 solid hits, with the abv being of a cinnamon color at 190°C and a pretty dark brown at 200°C, the max is 260°C, so well over combustion temps, but that might come in handy when using a Dynacoil or stuff.
One thing that totally took me off guard was the performance when using lower temps. Yesterday I tested 150°C just to see what it would give me and yeah: *that* is terpene heaven! But not only that: I was very surprised that I was able to get three pretty solid hits that way (not huge, but very visible). Then I thought the device might have been calibrated wrong, as I was not expecting *any* cloud at that temp (and taste), but the vapor was indeed super cool and the abv looked yellow-greenish. I don't even understand how that works. The fourth hit was kinda whimsy, but I was able to finish that load with two solid hits at 190°C. It's just such a great experience to tempstep with a Dynavap this way and those low temp hits are seriously incredible.
I have not tested my ss tip yet, but have tried 2018 caps and more recent ones (with serial number), they both behave the same. I guess captive caps might need some recalibration, the PhantoM caps definitely do. The Slim can be calibrated easily via a simple menu (which I haven't had to test yet).
One more thing that is awesome is that you can start reheating without the need to wait for cooldowns. Depending on what temp is set you won't even hear any click anyways. That streamlines the experience quite a bit and also helps saving battery life, as the device will need less time to heat when the cap is still relatively hot.
So while there are still some prototype-esque spots here and there, I am super happy with the Slim. I'm not sure what to expect from Mag Heater (he is back for now, though), but I hope this guy finds a way to do his stuff in peace and keep developing his marvelous devices. The Slim is nothing less than a sensation (to me).
