I might have a alternative option for you
@Ramahs , might sound a bit weird but hear me out. first lets start with a question, what exactly is a cart and what does it do????? a cart is just a heating element that is in contact with resin soaked cotton and a reservoir holding additional resin. I've been vaping with cotton a while and I like the technique , but I would never think of reusing the same cotton every time
but that is what a cart does. and while the reservoir is convenient because it lasts a long time, all it does mix the fresh resin into the cotton with the ass leftovers from your last hit. to me this would be like loading a dab in my Vrod , enjoying it, wanting another dab but not qtiping the dish clean before putting the next dab in???? madness I say!!!!!!!!
these dab pens sound a bit dubious to me and things like the Sia seem unwieldy for out and about, though there are people that stand by all of those devices. so what alternatives are there ??? is there anything as convenient as a cart?? can we adapt the tech of some other product??? why not something like a V3 pro or tinymight? loaded with concentrate in cotton??? why not! to me the hole point of a cart is to take a quick hit here and there anyway, not vape a big session. so why not adapt a on demand device to bend to our will???? I know what your thinking, does this actually work? yes and its not bad. I've done poor mans twaxing in my tinymight many times, just placing a little concentrate on top of the herb using a wpa. but I haven't used cotton in either my tinymight or V3 until tonight. I loaded up a half rice grain dab of my CO2 resin, wrapped in a small piece of cotton and placed it in the micro dosing hack I have in my V3. first hit the dab was melting, little vapour, next hit was good though you can't pull off the quick mouthpull and back in the pocket trick. its more like flower vaping and needs a longer hit but even with the V3 a 5-10 second hit will give vapour, bigger hit more vapour.
you also get the advantage of being able to bring weed and concentrate and switch back and forth all you want with only having to bring one device.
