Nik- I have one of the multi standard models. No biometrics for me. It's ok. To set the combination you can have it so multiple fingers need to be pressed at the same time, adding to the number of possibilities. I've had mine for almost 5 years and still have yet to change the batteries. Need to make sure the key is easily accessable though in case the batteries die (otherwise you won't be able to open the safe).
Mine is opened a least twice a day, everyday. It's next to the bed within arms reach.
All in all I like it. It doesn't look for feel cheap like some of the other safes around the same size.
