We have but one thought about this Bottle Lock: sure, it looks like it’d come in handy, especially when one has untrustworthy roommates, but here’s the thing: what if you forgot the combo you set?

An inappropriate spot of memory loss (which might well happen if you happened to have already emptied a few other bottles that had been lying around lock-less) and you might have to break into your own bottle …

Still, this would be quite a handy thing to have. The solution is to scribble down the combination in a safe spot, of course.

The Bottle Lock is an elegant and hardy solution, and certainly more dignified than scrawling a line across the bottle in permanent marker and writing "Hands Off!" (we’ve all been there). With a padlock-style four digit code device, all you have to do is pop the lock in the neck of the bottle, change the code, scramble the lock and rest safe in the knowledge that only the most bored of liquid thieves will have the slightest chance of getting to your precious liquid. Turning the lock mechanism will expand it so it locks tight in the neck of the bottle, so that when you lock it no-one but you can get in.
