Well to start off with I bought a keep key about 2 months ago, because I had a friend buy a trezor and I thought it looked really cheap. Now the design and casing are amazing on keep key and as far as having a leg up on the others that's it, you know they say you pay for what you get well this is not one of those cases. Now keep key does have very good support and a cool case but like I said that's it. Now it will not support ERC20 coins, now to some that does not matter but if you get into any ico you can take your coin offline, now they say there working on it but that's been said for 6 months. Also as this is the most important is you can not adjust the miner fees, keep key has litecoin miner fees locked at .001. What does that mean, it mean nobody on the network will pickup your transactions cause your not paying enough. I've been trying to send a litecoin transaction for a week and no miners will pick it up, the coins are stuck in my freakin keep key, now its almost a joke of a device. Please stay away from these things there terrible on a scale of 1 to 10 I give them -1, please do your homework keep key and fix these issuses, in the mean time guess im gonna look into a trezor or leder. One last thing if your looking for a hardware wallet, only buy it from the suppler or amazon as if anyone gets your phase words they have your wallet. Never buy a used hardware wallet, I hope this helps whoever is out there stay away from keep key!!
