An unsponsored first impression from Get Up and Get Grounded who purchased our product at full retail price.

Footage from an attempted theft shared by a customer. Unfortunately, the clip ends before it captured the would-be thieves leaving – but our customer was ecstatic!

“The strongest and most secure lock I’ve seen… definitely worth the money and will be buying many more. Came quickly in the mail.“
