Not safe, won't use again. We left our two bags at a souvenir shop in downtown NYC. The shop employees were super nice but Vertoe's idea of security combined with the laziness of the shop employees confirms that I will never use this service again unless I am using a safer suitcase. The employees sealed the zippers, but as most people know you can easily break into a zipper by pressing into the teeth with an object like a ballpoint pen. I would have felt safer had the Vertoe seal gone around a re-useable plastic bag, thus guaranteeing access to the zipper. Oh, the shop also left our two suitcases at the back of the shop, under some "BiG APPLE" sweatshirts they were selling.
