We bought this 4 months ago. Great value for the money. We are a construction / renovation company in NYC and often send techs on the subway so we wanted the flexibility of a roller and a backpack. This is big, has 2 full size compartments that can take 2 or so power tools plus a bunch of hand tools each. A back compartment for a tablet / laptop and a front compartment for hand tools, fasteners...A typical load will be a portable vacuum(Bosch GAS18) with attachmens, a driver, a small sawzalls, pipe cutter, some pipes, a plastic holder with compartments for various fasteners, pack of 50 shoe covers, gloves, wipes, blades, at least a dozen various hand tools (crescent wrenches + vise grip + screwdrivers + hammer, tape measure, water bottle...While it doesn't feel quite as solid as a Klein or Milwaukee bag, it does not feel cheap at all and is serving us very well.We plan on buying a few more.Highly recommend
