Not busting on the recent 2nd group buy guy or nothin like that here. The 2nd one was 1/3 cheaper than the first one I got myself from the alibaba site but......Not sure where the 2nd group buy pieces came from because it seemed to be a knockoff of the alibaba one I got first. I say this because it looked similar but cheaper made. It isn't as nice as the alibaba one in that it wasn't as black-almost gray, the spring is much weaker on the key part, the key part is noticeably wobblier, the case doesn't close as tight & the "M" emblem is cheaper knockoff looking where the alibaba one had oem looking emblem, blacker nicer case, much springier spring action & less key wobble. With that being said, I used only the part with the button holes from the 2nd one to get rid of the panic button that I drilled on the first one. If the 2nd batch came from alibaba then I'd say they have product consistency issues.
