I guess I should have waited to buy mine from FastTech.
I got duped as well, thinking they were going to be stainless steel as it was originally listed on VaporTek.
So I got home from vacation and these were waiting for me
I still like them in aluminum. Although the concerns for damaged threads, scratches/scuffs etc are reasons I usually stay away from aluminum devices (of course now I own 4)...I guess I'll need to be a bit more careful with them.
So the Sentinel V3 clones I bought from VaporBreak were made by H-Cigar.
The M16 and Private V2 clones I ordered from VapotTekUsa don't seem to be made by H-Cigar: different packaging, different "satin" bags, threading is different, o-rings different, and the center pin is different. The SV3s have an H-cigar logo on the inside top of the button pin - the M16 and PV2 do not. The M16 and PV2 have GV logos on the tubes and the button (with a serial #). The logos are lightly etched on. The SV3 tubes are NOT interchangeable with the M16 since they are different threads. The PV2 ends (top cap and bottom cap) are press fitted onto the inner tube ends and cannot be removed.
I noticed the center positive pin on these ARE floating pins - they are just very tight inside the delrin. I pushed mine out and used a round file and lightly opened up the hole just enough for the pin to slide = float.
Sorry - Ifony pic.
If anyone wants more pics of anything specific let me know, I can take some more (although my "real" camera isn't much better than my iphone
)
