The unlock key is large enough to be used. The metal part you press on hurts, but apparently all classy locks are like that. This model of laptop lock is very practical as it also has an accessory to protect the laptop charging cable. Cable length is good. If you need to buy a lock, that's pretty good. It comes with two keys, which means you have a spare key in case you lose your master key. The flat lock style really works for me as it doesn't get in the way of other cables and accessories on my desk.
