well, I got the clones in from fastech, I have not built one yet , but instantly changed out the top cap on my Limitless+V2, love it. It is the same cap as the original, now the only visual differences were a bit more fuzzy engraving and the omission of the limitless logo in the circle of stars, and did not come with the single coil adapter or Titanium screws, but wieght wise they seem to made almost exacly as the original, I will report back after a build, but for the $10 and change I paid for it was a deal, if not for the topcap, glass, and orings. I think it was a good buy. I also like the Limitless+ parts packages I bought with them, comes with some nice coils and o-rings, single coil adapter as well as the 510 connector, They also came in the same plastic box but with no cardboard wrap-around, and the screwdriver is a cheap blue one and not the black one the og comes with, not that matters much. We will see after I build one if I am still this happy with it.
