“This storage area is fantastic, they are very clean and well kept and well-managed. I've had items here for nearly a decade myself and my local Marine Corps League keeps items for our community service projects here as well. Easy access and 24-hour gated entry and exit, with restrooms available during working hours as well as use of cards and move-in truck. In general I would definitely recommend this as a storage location because their prices are really fair as well as the location is great..”

“I found Storagemasters in O'Fallon MO. to be the perfect storage location for people moving to a new home. It's central location on I-70 is easy to get to, has large drive-up storage, is clean & secure. And the employees are courteous & friendly. Having a storage unit here made our moving to a new home much easier. Thanks!.”
