OpenDime: The First Hardware Bitcoin Bearer Bond
The package I received was small and contained three OpenDime devices, instructions, and a sticker. I took one of the devices out of the packaging, noticing that all of them were sealed properly. Although the devices are inexpensive — costing just $40 USD for a three pack — the OpenDime looked very well built.

I bought six of them, and the first day I test-fired one: loaded it with files, sent some BTC, and then went to my blockchain.info wallet to import the Private Key from my OPENDIME (after breaking its seal section) and sweep the BTC out.
I like the device, it's cheap and so far seems OK. No need to update firmware like I have had to do w/ Ledger Nano and Trezor.
But, it's not a full function wallet. You need a BTC wallet that can import Private Keys.
