You've made tests which mean the products haven't been tampered. It's asking for big trust from ppl if they're using any thing given by Betnomi it's a risk they shouldn't take. Users shouldn't use them because if their balances became empty they won't forgive Betnomi.
ConclusionHaving these said, I guess that the owners of Betnomi Ledgers can relax now, as their products are not tampered with. Those which want though can perform the above steps for checking their wallets' hardware integrity on their own. However, I don't recommend this, unless you don't care if the device gets fully damaged or unless you are used to opening electronic device / fix them / etc.

It is very sad that icopress is having a huge loss because of Betnomi but, at least, they were not
that evil to tamper the devices they raffled on the forum.
