Quick disconnect top notch

I bought this originally for my son who is apprenticing as an electrician on a large job site and lost a key. There is a locking feature to protect against accidental loss of items which lock the disconnect clips in the closed position. Quick and secure

Key smart has not arrived after a full month.

I ordered a key-smart. It has not arrived after a full month and nobody answers my complaint emails.

Key smart Pro with disconnect

Bought the key smart after seeing an Instagram post, looked good as an organiser. Loaded with about 12 keys including the disconnect/bottle opener - Difficult to put together (and I’m a well experienced engineer) threads are too short, needs some redesign in my opinion. I spent about an hour making sure it was just right! You also have to drill out a lot of key types, as not all keys fit centrally. - The bottle opener is pretty useless, the added extended steel for the key, means you can’t use the bottle opener when in use, which is pretty pointless. The key disconnect is unreliable, you will soon disconnect this from your car key for example. - when you put it down in a flat surface, the light button protrudes slightly, this means the light comes on and drains the battery. - if you have more than a few keys, it’s really awkward to find which key you need. What you don’t realise is every key is individual, you may recognise a key by colour/tone/wear or the name stamped on the key, super easy when on a bunch, but not so much when 12 keys are ******* together. - Tile function/key finder is really good - Space in pocket in comparison to a bunch of keys good - reaction from people thinking you have some new gizmo good - value for money, not really, cost a fortune from the USA then I had to pay £20 import cost on top when I went to collect it. Not a perfect product, but functional, needs a few flaws redesigning. Would I buy another one, no.

Not premium key holder!

Not good. This is too think and too big. This gets in the way of you trying to use your key! A waste of money.
