I was sold on Tough Shed but Amazing Buildings had a similar building for quite a bit less. There were enough differences in the materials and design that I paid an extra $2K for design and material changes to make sure the building would last.
After 2 months, the doors would not even close. I called Rodney and sent emails for another 2 months asking for help. When he finally responded, all he wanted to discuss was more money and he still never came and fixed the doors.
Do not use this company. Get a Tough Shed from Home Depot so you have a well designed building with the right materials, a warranty and service after the sale.
