I was just about to mention the Kick clone has been quite excellent so far. coming from someone who really didn't have much interest in these but I had an application I wanted to try it on being I'm exclusive to Mechs. I have used it with the Red FT Trustfire IMR 18350 batteries with claim 800mAh. Test subject a 2.4ohm microcoil in an rda and cranked kick to 12 watts and haven't looked back. Ahh no PWM... I vaped so long on it that I was sure no cutoff was going to happen and was going to undervolt the battery. I kept listening for it without worry of destroying the cheap azz battery. I was amazed how long the battery lasted before it did hit and pause then hit and pause. I switched batties and when I got home and slapped it on the VP1 it said 3.21 volts. Kick fits perfectly in my Astro clone. Works in my brass M16 and TVS without mods as long and you position the middle tube correctly. The King/Chi swallow this thing and will need biz card trick to fill in the gap. Didn't seem to fit in the Tri colored Private v2 which is my sub ohm workhorse but most things are possible with modding. I will have to try in others and update but I hope some of this is useful.
Well i have 6 18350 of those Trustfire IMR in shipping hell right now, and that's exactly why i asked about the kick i plan to use it on the astro tube if it fits the hammer clone with the russian91% or the kayFTun
