I decided after much deliberation to buy this for a "key ring" rather expensive product. I discovered him at Thalia, where he has taken almost 18. From the moment of unpacking to, but I'm thrilled! The only difficult part was turning up the key to the relatively small color-coded key rings, but the same then you can start. by a small switch on the circular centerpiece of the key holder can be removed, the individual parts within seconds or reconnect. And without the operation of the "slide switch" They also hold bombproof. I would recommend this key carousel anyone who has a great bunch of keys, which he would like to order and also often the challenge is to decrease individual key or to disconnect and reconnect. This can usually be very time consuming and nail unfriendly. After one-time threading the key, which is then no longer a problem. My friend was actually so excited that we are now thanks to Amazon, both owners of such key holder.
