bought my first one in oct 2012 why take a look at the inside very little wheel interference. I work for the city [61yrs old] so I use it every day.it makes for a nice seat & yes you can stand on it ; I do a lot & never crack the lid how I stand on the outer rim not on the center.I do this when working on door closures. Do to the amount of tool in it I don't pick it up by the handle but use the red locking handles.Locking it just says leave it alone but breaking into it is easy.The pull up handle always work but the wheels are a joke wore out in one year. So I had to cut all that off & bolt on a luggage cart. I bought a new one in sept of 2018 because dragging it across the truck bed wore out the bottom.So the new one now has 3/8" wood on the bottom & the top has 1/2" plywood so I can stand in the middle pulse rain does not get into my box any more.My coworker bought one at the same time 2018. I put 2= 14"x10"x3.5" plastic boxes in the bottom for hand tools.Then drill- calkgun- 3calk- 20"crow bar- 20 wrenches in own holder- doorstop- rags- drill bit box / top holds 2 batteries- mud pan&put small items in it- 3 rolls of tape- tape measure- stud finder- reciprocating saw- 2 boxes like a drillbit box- speed square- sandpaper- spackle- 2 pill bottles- plastic water bottle like you buy at store & a few more odd an ends. This is a great box holds a lot if you pack it right.
LIke the size, rolls well. Rubber coating comes off plastic wheels within a very short time of use. Lid cracks, which start where the handle recess is placed and works out radially. The extension handle is gimicky and the little springs inside often displace with the handle either extended or shortened. Would pay double the price if it was half better.
