  • This set was nice and worth the money.
For a product of China they seem to be quality built, they arent hige but they arent small either, if you organize them properly they can hold quit a bit of stuff. Definitely worth the money. I especially like the latching style. And the front feet on the rolling box has rubber so it roll away as you grab stuff out. ... show more

  • Flex Stack
I LOVE this tool organizing stack! It is so easy to stack, unstack and maneuver. Fits perfecting in the back of my SUV as well. I’d definitely purchase again AND I’ve purchased 2 more flex stack components because I like the setup so much.

  • Disappointingly UnRugged.
Disappointed that the handle is broken and, having bought six or seven power tools and batteries, I’m hoping they’re a lot more durable to a the handle on this cart/toolbox.

  • Great for work
I started traveling for work and this pack out is easy to roll around, holds everything i need to bring to install and repair different equipment. Fits easily in vehicles. I compared to a Milwaukee version and this Flex Pack is cheaper, more durable and locks in easier. I have had other techs even say they liked this better than theirs. Would rate 5 stars if I can easily find empty bit holders for the lids to hold all my screw gun bits ... show more
