Yeah definitely. My Waidea is now very much part of my daily use. I didn't use it for a long time, a couple or months or so. At the time I only had a couple of tanks on the go at a time, and every time I thought of using it I'd find I'd get "Check Atomizer" because the pins wouldn't touch. Then usually if I adjusted the pin on the atomizer, I got way too high resistance.
Then a month or so ago I started buying lots more tanks, and got all my good tanks built at the same time. Now I use all my mods all the time, with different flavours in each, and because I have a lot more tanks on the go I can always find one that will work with the Waidea. Right now it's my SXK Squape Rs clone which has a massive, protruding 510 pin after I replaced the stock positive pin with a countersunk M3x16mm brass screw.
I have to say that in terms of appearance and feel, I prefer it to the SXK. The matte finish just feels nicer. I also prefer the Rayn chip in this Waidea to the one in my two Kangxin Mini VFs - they both have a mild annoyance with the Kanthal/TC detection. After sleep they always revert to being in Kanthal/non-TC mode. If I just pick them up and hold fire, it will almost always fire as a VW vape. So I have a procedure now where I pick them up, then tap three or four times: once to wake up, then two or three short fires which is what it usually takes to realise the coil is TC and show 300°F instead of X volts. To be fair to them they were expecting Ni200 and therefore a quicker resistance ramp up. But I don't have to do that in my Waidea, which is always in TC mode on wake up (or restart, as it should really be called.)
So although my Waidea is now just one of many mods, I'm definitely glad I got it. Oh, and it provides a convenient home for my two button-top AW 18650s that don't fit in many of my other mods
