It has many vulnerabilities.. some of which are continuously being found and attempted fixed. Still, there are many rumors about the Check guys peddling this little thing...... I would be very very careful getting one of those.
But also consider... many of us have USB's that suddenly stop working.

Negatives:
If stolen, can it be cracked or are the balances lost forever (if the owner doesn't have the private key held elsewhere)?
- The wallet is very small, therefore easy to mis-place, lose, or have stolen if left around
- It's electronic, so it is vulnerable to a battery wearing out or exposure to water and other elements
If stolen, can it be cracked or are the balances lost forever (if the owner doesn't have the private key held elsewhere)?
1: has seed words
2: can replace with a new unit for seed words (pretty sure battery shouldn't matter as only powered when connected via usb)
If stolen it would need someone to bruteforce the code manually, would take some time. You should be able to enter the seedwords and get the funds out before it happens.
So I could buy 2 set them up as clones and put one in a bank safety deposit box?
then if my in house breaks or is stolen I could go to my safety deposit box and access the wallet?
if true to both questions and you have a decent amount of coins I would consider buying it.
and if I was buying 2.
I may as well buy 3.
since 2 = 238 usd and 3 = 299 usd
why spending money on TREZOR when you have breadwallet app for iPhone? it also works on a secure environment - iOS. (you would use an old iphone just for this wallet making it even more secure).
There's some really cool features also, you can set two different paraphrases to hide large amounts

If you have your passphrase memorized and you haven’t written it down anywhere, attackers with physical access to your TREZOR may still be able to extract the passphrase with a $5 wrench. In order to mitigate this risk it is possible to set up your TREZOR multiple times with multiple passphrases. The goal is to have one “spoof” setup that only holds a few bitcoins or bitcents and one “real” setup that holds your fortune.
In order to do this all you need to do is setup your TREZOR with a passphrase, then unplug and replug your TREZOR and enter a different passphrase. Here’s an example:
I setup my TREZOR with the passphrase “lonelypumpkins” and load a large number of bitcoins onto my device. I unplug/replug my TREZOR and enter the passphrase “funnyspirit”. I then send a few bitcents to the “funnyspirit” account. When the thugs come and steal my TREZOR, I can now safely tell them that my passphrase is “funnyspirit”. They will be able to steal a few bitcents from me, but they won’t be able to get at my fortune or even determine that a second passphrase exists.

That's too complicated for a lazy guy like me..
I don't have more than 10 BTC and I definitely won't lost my TREZOR. I will read more about TREZOR, I'm going to love it even more!

How does it work? I think it comes with a display, so.. ?

In order to limit the attack surface against the TREZOR, TREZOR communicates solely through a simple USB protocol. There is no WiFi or Bluetooth, no camera for scanning QR-codes. There’s not even a fingerprint reader for identifying the user. This is all because we want the TREZOR to be as secure as possible. The fewer devices the TREZOR talks to, and the simpler its communication protocol is, the less likely it is to get infected.
The TREZOR also has no battery. When its unplugged its off and your bitcoins are safe from cyber attack.

Oh this, thanks. I thought it's safe, but that much? Amazing!

it is vulnerable to a battery wearing out
Do you even own one? They don't have batteries...
LMAO

Any thoughts? I want to store by BTC safely and securely offline. Anybody got any experience of using trezzor for that? Positives and negatives?
If you want to store BTC safely and securely offline then why don't you use Electrum ? It's great to operate cold wallet with Electrum
I think it's something like paperwallet. I would recommend it to you, I will buy it later. I hope it won't be waste.
based this vulnerability, http://johoe.mooo.com/trezor-power-analysis/, which was fixed quickly you can say that it's relatively safe, no one know if in the future another hole like that will happen again...
remember that besides the vernam cipher nothing is 100% safe
remember that besides the vernam cipher nothing is 100% safe
Even if the logic and mathematics are perfect and the op-sec is good, there can still be implementation details that allow side channel attacks, such as the Trezor power issue. In practice, the Vernam cipher is not 100% safe.
This article from NSA is interesting. https://www.nsa.gov/public_info/_files/cryptologic_spectrum/tempest.pdf
vernam cipher is not 100% safe in practice, not because there is an hole in the cipher or something, but because of the messenger
it's like you have x+18 =y(where 18 is the ciphertext and y is the key that you don't know) how can you solve this? it's impossible without knowing at least the key(y), because x and y could have multiple value
if the messenger of the y is caught and y stolen then yes you can decrypt it, but as i said above it's not because the vernam cipher isn't 100% secure

if you want store something for long-term (years), securely and offline, go with bunch of paper wallets generated and distribute them to multiple locations.
Trezor is more or less for somebody, who is actively using bitcoin and needs another (hardware) layer of security..I'm just too conservative to use some "small USB gadget" for more than 100USD, if I can use paper + for Trezor backup you need to store paper with recovery seed anyway...
Personally, I think Trezor wallets are the "bang for the buck" when it comes to hardware wallets. I never have one, but the reviews I've seen is sufficient enough for me to tell that this hardware wallet is indeed very good to have. But in any case. an offline machine is also a great way to keep your coins in a cold storage, though it does not offer mobility compared to a Trezor wallet.

I have both a Trezor and a Ledger Nano (bought both some 8 months ago). I am happy with both. I have used both of them over 15 times each, and I cannot detect any problems with either.
The Ledger costs less.
I have not upgraded the firmware with either device. Also, there may be new versions of the Trezor as well as Ledger Nano, I may buy another Nano to see (as well as have some BTC in yet another device hidden elsewhere).

I think they're over-rated personally. If you just keep your coins offline and use a secure computer that's all you need. Just make sure you've got a back up or two and you should be fine.
Never heard of Trezzor ...
Vulnerabilities have kept showing up for it. Let's be honest, it's not safe. But it's probably better than some of the other options.
