Good quality, except for the handles ( there are only two rivets on top and when two more rivets would be used, then the handle would be attached properly to the bag itself ( more robust ). Now, when taking the bag by the extended handle, the attachment bends and I think this might give a problem after a while. I'm going to enforce this myself: 4 stars instead of 5
This is the only minor point. Also quite big, but that's done to fit some more bigger sized cabinets.
A good alternative to the more expensive branded tote bags.
I use these for several 12" speakers ( Turbosound IQ12/IX12, HK Audio L3/5, Samson RSX 112A,...)
The pictures are not as the actual product: I don't have the supports on the bottom ( only two wheels, but that's it - the bag rests on the fabric and not 2 plastic supports as shown)
