Note: You do not have to know what the old combination was. Anyone, therefore, can change the combination on your lock to whatever he wants and then proceed to open it.

Have you tested this? I ask because I bought a bunch of similar locks from Brookstone (pre-TSA) and they work slightly differently.
The initial, factory setting was 0,0,0 and the button had to be in this position when it was pushed-in to change the setting. But then to change the setting again, the lock had to be set to whatever I had re-set it to in the first place; it could NOT be reset from the 0,0,0 position.
This wasn't at all clear from the instructions which came with the lock.
Just wondering if the design has changed to make the locks less useful.
