Average Reviews:
(More customer reviews)I love this lock because of its ease of use (it can be opened in two seconds with one hand,) but I thought I'd warn people that, despite its sturdy feel, it uses relatively weak security. Using it on the gate to the backyard is probably fine, as a deterrent, but using it to protect valuables is a bad idea.
The packaging mistakenly states there are 100,000 possible combinations, while in reality there are many fewer. There are only ten buttons, which can each be depressed or not. That means there are a total of 2 to the tenth possible combinations, which is only 1024. Worse, since the lock only supports 5 digit combinations, that reduces the total number of possible combinations to 252. That means that someone tried 25 combinations per minute, they would likely solve it in under 10 minutes.
Also, the combination is set at the factory and cannot be changed, which isn't a huge deal, but might irritate some, and also prevents you from changing the combination periodically.
The lock does have a secure appearance to it, so it will likely deter the math-challenged. For the right application, where a deterrent, rather than security, is sufficient, and convenience is important, this is a great lock.
