Just finished assembling this rolling workbench. It is very well designed and easy to assemble although it does take some time to assemble. All screw/bolt holes lined up perfectly and the unit is extremely strong and rugged when all assembled. The only thing I would suggest to "Seville" would be to add lock washers to the screws and bolts to prevent them from loosening if the workbench is "rammed" around. I used my own lockwashers to prevent this. I don't know if there has ever been a problem with the screws/bolts loosening but I didn't want to chance it. I definitely would recommend this unit. I'm considering purchasing the matching cabinets.
