I have Trezor and I'm very satisfied. There is one important thing to remember when you setup the wallet, there is an additional passphrase which is critical.

~snip~

Keep it in mind when you order trezor. I can advise you to buy two wallets, one for back-up in case you forget your passphrase and erase your other device, then you can transfer the funds to the a fresh wallet from the backup.

You can setup the trezor without any passphrase too, simply by letting the password field empty.

And instead of buying a second trezor, writing the passphrase on the backup paper of the mnemonic code would also be a viable (and cheaper) option.

you have this astronomical number I can't even start to comprehend and yet, if you did create the same key than you would access somebody else's wallet ..

2 to 128 power = 340,282,366,920,938,463,463,374,607,431,768,211,456

small possibility but how can it be considered impossible?

A private key is a 256 bit number.
So that's 2²⁵⁶ = ~ 1.15 * 10⁷⁷ = ~ 1150000000000000000000000000000000000000000000000000000000000000000000000000000 0

That's roughly the amount of atoms in the Universe.

Lets say i pick a random atom in the whole universe. Do you think you were able to guess which one i chose ?

The chances are not just very slim.. its practically impossible to even bruteforce a small fraction of the whole search space.
