I bought this cable to secure two laptops placed on the same table. The construction is as serious as for other Kensington products. It comes with two keys, you can save the key number on the Kensington website to get a copy in case of loss. Locking / unlocking is very fast. Caution, however, it is not necessarily easy to browse the first device to secure the cable to the second unit, the two locks being on the same cable which is relatively rigid, installation can be a bit laborious. Having a Kensington MicroSaver single for each device can be more convenient. No problem with the seller Gadgets F1.
