That wallet is confirmed safe, but here's the thing: it's an offline wallet.
Now, I've never used an offline wallet, so take my words with a grain of salt, but my understanding of how they work is you'll download your wallet to your device (phone or computer or w/e), then buy and deposit your ethereum into the wallet, so the ethereum will actually be stored in your device, not on a 3rd party's server, the way most wallets work.
This has one big advantage: since it's not stored on a 3rd party's server, it's not vulnerable to that party getting hacked. (If Blockchain.info or Bitfinex or some other big online wallet provider gets hacked, we'll all have massive headaches; you'd be laughing).
But it also has one big disadvantage: If you lose or destroy that device, or lose your passwords and backup passphrase, then I think you're totally screwed. At least when an online wallet gets hacked, they have to make good to their clients, even if, as in the Bitfinex hack from last year, it takes them a few months to get everybody their money back.
I can think of a couple smaller disadvantages, too: 1. It's only a wallet, a place to store ETH; if you want to actually sell your ETH for dollars or for bitcoin or for whatever, you'd still have to move it to an exchange. If you open a wallet at Bitfinex or Poloniex, you'll have the option to sell or convert to another currency, 24/7. 2. If you're sure you want to hold ETH for a while, then you might as well make some interest, even if it's really low interest, on your holdings. You can do that by borrowing your shares out to short sellers at Bitfinex or Poloniex.
Heh, on the pricing question, that would Rock!
