I reached out to BitcoinLixin here and twitter over a week ago. He has not been active on here for a while but is on twitter.
FYI I think that you can reach him much faster on Keystone discord or telegram channel.
Someone else is probably handling their twitter channel, but he has his own accounts for contacts.
The device SEEMS secure, but if you can't be sure it's the device that is supposed to be in the box what's the point.
You still need to verify on website to confirm your device is genuine, and I agree they should improve packaging, but don't expect to get better security with better package, or with void stickers.
I know you can't open Trezor wallet without destroying packaging, but scammers can easily clone this...especially in China
I have gotten responses from him here and on Twitter before so I went with those for contact.
I fully understand that boxes & packing can be faked.
BUT, and this is just my opinion there is a difference between Dave getting in more or less on his 1st attempt while eating breakfast and a determined person getting into the box.
Cards on the table, they are sold on Amazon, as of now anyone can order one take it out of the box, reseal the box and ship it back.
Amazon does not check returns that closely and if you send it back with a did not want it goes back into stock, the next person winds up with an empty box.
Now Keystone looks bad for something that could have been handled with a better glue and a security hologram that, to be blunt, didn't suck.
I know all holograms are not secure see here:
https://bitcointalksearch.org/topic/just-a-video-about-how-bad-some-security-holograms-are-5401502 but some are better then others and there are other ways of adding to security to them, even if it's just cutting them a bit so removing them at all is more difficult without damaging them.
