@BabyFacedFinster I can only vouch here for Auber controllers. The rdk-300 is very good in performance, so so easy to set and adjust. Rock steady temp holds with the coiled Elev8r, just dead steady throughout hits (depending on vape setup of course) with zero drop.
But it is instantly reactive to environmental shifts this impresses me most with it. It sits bang on temp forever in use and static while on the glass heater, but the split second I lift the coil off the heater the temp starts falling (as soon as removed from the heat sink and exposed to cooler air).
If I put the coil back on the heater, it instantly steadies. The rdk-300 seems to have its own mind, and it is the steady old tortoise who won't rush out of it's armchair to answer the doorbell.
Instead it pauses for a moment while it waits for the dust to clear, as it calculates the swiftest bird's eye trajectory to the new or same target which has moved slightly.
But after those few seconds, the temp goes steadily up or down, maybe 2° per second for adjustments, and lands solidly at set temp again. You can give it the run around left right and centre, same result. Exact, dependable consistent performance. Same response and adjust time to any set temp change, holding steady and as consistent and exact as can be.
Anyway I have very little controller/coil etc experience but I can see why the Rdk-300 in particular has such a good reputation. Personally, I'm not a big fan of the one hour auto shut off. Everybody else seems to think this is it's biggest selling point, citing it above performance
.
Safety matters sure, but I can't tell you how frequently I go to take a nice big hit in the zone and the controller shuts off on me or I'll come back into the room and it is already half cooled down!
If I am nearby when it's switch is off it's no problem I just turn it back on straight away the temperature immediately starts to fall but within 15 seconds it's climbing back up again and in less than one minute it's dead steady on the set temp so I can't really complain lol!
Auber FTW!
