Here at BioShield we are always trying to improve our service and technology. We are pleased to announce the sale and shipping of a limited edition, new design single and double QNL (Quantum Nano Layer) BioShield key, incorporating beautiful protective crystals for the QNLs. The glass body of the key is also protected by the metal casing making it more robust.
We have been asked what is the difference between the old key and new keys? The main difference is in this more robust design and in the dual key, obviously the inclusion of two QNL’s, instead of one. The key works in exactly the same way, both when simply carried, or plugged in for the larger coverage area. In the dual key the 2nd QNL has been placed in the new top, that can also then be carried with you when you leave the house, attached to a key ring or even worn around the neck. We do hope you enjoy the new design.
