  • Must have Storage System
Well built. Met and exceeded expectations. Hardy, strong and easy to move around.

  • Very durable and extremely high quality
This is one rugged case!! This roller portion is great to store large and bulk items in. The Flex Stack system let's you add more pieces for virtually any storage need. I have added several more pieces to this, and am amazed at the quality. Seems like they thought of everything!

  • great system
Purchased the stack system and loved it. I have been looking for. System like this for a while and would give it two thumbs up

  • Wow. Sturdy first impression.
I am new to the modular toolbox craze, and I worried it would feel fragile and the non-pneumatic wheels would be useless. In fact, it feels sturdy and well built. The wheels don’t have the compliance of air filled tires, but the are large, rubber coated, and roll smoothly. I hope this holds up. Will update review after more use if my opinion changes. I wish the offered a version with front loading drawers rather than top loading, especially given this will always be the bottom of the stack. ... show more

  • Good product
I'm not giving it 5 stars because after a month of use, one of the locks holding the folding handle broke and I have no way to replace it. Otherwise, it's an excellent product.

  • Great tool box
Heavy duty modular tool box. Great build. The handle broke in shipping but I'm sure I can fix it. As an organization aficionado I like their system. In the oilfield where I work durability and portability are always valued in any product
