Keepkey is a cheaper hardware wallet than other big competitors such as Ledger or Trezor. It has a professional design and a big display screen. Using it is very easy and simple so everyone can make the best out of it. However, its firmware quality is not as stable as the other famous one and the customer support is not so reliable. I'm not sure if Keepkey will be a good wallet for the long term. I hope they will make some changes to the current product!
