Did the OP state a budget?
Okay so about the Sapor...my first I was running on my AV Peg mod which is a hybrid mech mod. Granted my build was low ohm but my mutations could handle the heat better than the Sapor.
On like the fifth day I had it, I unscrewed the bottom to swap batteries and usually when I have an rda on top & a battery inside, there's a little gap between the bottom button housing & the rest of the mod.
Well I popped my Samsung 25r in and when I was screwing the button housing on, around the point that it would normally stop moving because the + was making contact with the center pin I felt a bit of resistance but it kept threading until there was no gap at all.
So I took everything apart, because I know about direct to battery mods and shorting and I didn't want to blow up my hand/face/favorite mech mod. Nothing was wrong with my mod, so I looked and the Sapor's center pin had pushed itself in to the point where it looked like the insulator was protruding farther than the center pin. I look inside the atty and on the deck, the T block center post was pushed up about 2-3mm. I pushed it back down to hear an audible click noise. I tried unthreading the center pin so it was safe to use, but the center post block popped up again. So I pushed it down again to hear that click and screwed it back onto my mech. The same thing happened. The center pin spun freely back to where it was before, which was recessed inside the insulator.
I took it to the shop I got it from, they kindly replaced it with a new Sapor and within 3 days and a higher ohm simpler build the same thing happened when i ran it at 60w on an IPV4. The rhodium plating pretty much can't handle the heat and gets super hot, melting the insulator around it. I don't even know if the insulator around the center pin is PEEK.
That's the detrimental fault in the Sapor for me.
View attachment 485771You can see a small gap in the seam at the bottom just below the mod's vent holes, that is the gap I am referring to.
@Two_Bears - I met mikevapes at the NJ Vape Expo....i don't like him. I'm not gonna go into detail here but if you want to know why just message me.
