Hi,
I was thinking of giving an opendime to each of my university teachers to introduce them with bitcoin and load some money into it. I have a question, what is the average lifetime of the hardware against dust and etc...

Is it a subtle way of bribing them?
Are you afraid that they won't be able to spend their satoshi and will punish you? Regarding your question specifically, I guess the same rules apply here as to usual memory sticks. Dust is not very dangerous to them, unlike high and low temperatures as well as fast transitions between such temperatures. Apart from that, these devices should be considered as expendables anyway as has been explained in the thread, i.e. they should not be used for long term storage

Looking good nvK! Guess I'll have to get a few second batch ones as well. 
It's in stock!

Folks, we've made a Experimental Google Chrome App.
It only works in Chrome Dev mode of Chrome OS.
Installation instructions here: http://blog.opendime.com/opendime-chrome-extension/

nvK, as stated before I'm truly looking forward to setup a small group buy (24 pieces) of opendimes here in italy. Just a couple of questions that i post here because they can be useful also to other people:
1) Italy is considered as western europe or eastern europe?
2) Tracked shipping is just a registered mail from canada with the local post office or is done with a shipping carrier?
3) If the question #2 is registered mail, is there the possibility to use a faster shipping carrier like DHL or UPS?

NP.
1. Western Europe
2. Canada post, "business light package" registered (Aside from customs delay, it usually takes 5-10 days to Italy)
3. Yes for orders over 99 (33x 3 packs)

Basically, when the average transaction fee rises above the price of one OpenDime device (or comes pretty close to it). This thread has been inactive for some time, but now when the fees are skyrocketing together with the Bitcoin price, it is active again, and this is not a coincidence. It could eventually make sense to buy a dozen OpenDime pieces to pay for your yacht in a more or less safe way, without someone closely following your online transactions which you would have to make otherwise
Damn dude this is an apocalyptic scenery! One should keep his stack separated in different devices to be sure that at least a part of them should run properly. As I stated before I like the concept but maybe they are a little expensive in the actual situation.
I think alexrossi's criticism come from not fully understanding how it works or never handled one in hand.
alexrossi if you ever actually try one, you will probably change your mind.
Well what I know is that with electronic devices there is always a percentage of dead on arrival devices and instable devices that will die a little later. You know, private key on an unlucky opendime could be worth thousands and totally lost, without possibility of recovery
And that's the whole point of these devices
There is no way back once you give away your Opendime or it gives away you! It is not like those hardware wallets when you can restore your key even if they break (or someone else could do without ever physically touching your wallet), which, as to me, undermines the whole idea behind them (i.e. storing your coins safely). If you need safety just use a paper wallet instead. Though I agree with you that you can't be sure that such a device doesn't malfunction, I think you could discard erratic devices by test using them for some time (i.e. without actually writing the key to a specific unit). In any case, these device are expendables and you shouldn't in the first place be using them for storage (again, use a paper wallet if you need that)

We test the hell out of this devices and discard the factory DOAs, then we program them and re-test them.
Is it possible someone breaks theirs? Yes.
But I deal in facts not hypotheticals; This is the 3rd batch of devices, thousands sold and 0 returned this far.

Well, this is good to hear. May I ask if it's possible to have a discount in case of group buys? Many users in Italy could be interested in a device like (me too)
Just gather a few folks and place an order

Yes, I haven't tried one yet, that's true. In my opinion the seller should give the opportunity to buy just one, to take confidence with these devices and eventually do a bigger step after by buying many others.

They are there to enable off-chain, hand-to-hand transactions when you want to buy something but don't want to leave a footprint on the blockchain.
Yes, they are cool! (Honestly if there was a discount or something like a coupon to have them for a lower price, I'd buy a couple to do an audit on the durability in tough conditions)
My point is: the trade-off on leaving a blockchain footprint vs single point of failure is worth enough for real use cases?
First use case:
- WOW, with opendime i CAN actually do microtransactions!!! I load them once and I can have peace of mind about not being harassed by slow blockchain and costly fees!
- Ahh crap, I'm handing out a 15 bucks device for my coffee transaction, definitely not worth it :/
Second use case:
- Opendime is super nice, finally I don't have to wait confirmations when I'll buy my private yacht
- Craaaap, I have plugged in multiple times my opendime and It's definitely dead!!! How can I recover my 50 BTC loss :/
There is certainly a third use case

IMHO; Yes, it's worth it. Hard to put a price on real privacy/fungibility.
You can equate it to carrying a large pile of cash/gold for an in-person exchange. There is always risk.

You can't have both. It's either a never exposed private key or it has a backup.
Let me explain with a decent example. I don't know if you have already heard of the Ledger Nano. Basically in the setup process, the nano output once the seed to your computer (that is supposed to run a live distro), so you can have peace of mind even in the case that the nano is destroyed.
I know that the opendime is supposed to be a security token that you can pass to other users and cannot have this function, but the insecurity caused of random (and systematical in large production batches) malfunction is really a deal breaker to me.
However I wouldn't hide that the idea of testing one of them is really appealing, i like the concept!
We have recently discussed this matter in depth
What you are telling is the same when you have a backup. In that case the whole idea of whatever device you are using is losing its major aim (i.e. keeping your coins safe). It could be argued that it is still better than, say, a web wallet, but your coins are still not 100% safe. On the other hand, Opendimes are exactly that, if it breaks you lose the coins, so no way back. But these devices are in fact not assumed to be used for long-term storage, to begin with. They are there to enable off-chain, hand-to-hand transactions when you want to buy something but don't want to leave a footprint on the blockchain. In other words, you put your coins there and then give this piece to someone who can do with the coins whatever he wants
