After much research into tool bags on wheels I came across this bad boy!. It hasn't disappointed. Thick wheels, robust tool storage solution which will save your lower back on the jobsite. I have a milwaukee packout system aswell, obviously it doesn't compare to that, but this is great for packing in what you need for the day and wheeling it from task to task. Tried the cheaper alternatives in the past and they all fell apart!. This thing seems bullet proof and has caught alot of attention from other contractors currently using the cheaper alternatives. Well worth the investment!
