Really nice and convenient
After getting married the Mrs and I had to combine houses a little quicker than thought so I moved the bulk of my stuff to an 8x20 out at Model T. The facility was tidy and the units clean and the price was around 5 cents per sf cheaper than anywhere else in Tulsa. Because the facility allows storage of project cars and special use, it definitely doesn't have the same clean "nothing but concrete and sheds" look that some other places do.
Access to the facility is 24x7 and there's a decent amount of lighting onsite but I usually keep some small LED flashlights to setup in the unit if I am there after dark. If I needed storage in the future, then I wouldn't mind returning.
