this technology has been proven to be unreliable, even in biased lab testing by the manufacturing companies.
Alot of them need brand new batteries EVERY time you want to use it. Try doing that at 2 am....
fingerprint ones, well they tend to work slightly more then half the time when you degrease your hand with solvent and then degrease the sensor pads with solvent. otherwise it wont work.
radio ones have been proven a joke. Way to easy for cheap radio jammers to disable the device from long range. and heavy clothing can mess them up.
and it costs more, hampers you, because try getting some of those devices into your little keltec or lcp..
