To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I was scared by the reviews about it not unlocking when the battery is dead, but if you are looking at this price point, then you really should be using adhesive for one side in case you need to be able to rip it out. Otherwise, spend more money. You get what you pay for. The lock you get is the one you pay for, so it's really just fine. No complaints and they didn't have to give you 2 extra keychain tags included, so I really can't complain
