Reviewed by Churchill from East Coast, USA on Friday, May 4, 2018Have trouble remembering numerical combinations? Having a lock using four letter words sounds great, right? Well, not if the only letters available spell words which are not meaningful. The complete alphabet is not available on each wheel. In fact, some letters are not available at all. Therefore, you can't spell anything you want, but have to select random words like HAIR or TUCK because it's all you can spell using the available letters. If HAIR or TUCK happen to be meaningful words for you, then certainly buy this lock. If not, you're bound to end up having just as much trouble remembering a meaningless random word as a sequence of meaningless random numbers.
