Ritter Keyboard Bag Bern 1125

I needed a bag with wheels to help save my back on the ever increasing distance to venues. Having examined the available options, the Bern 1125 seemed the most compact model to meet my requirements.
I have it for a few weeks now and everything is fine so far. My Yamaha P-121 73-keys fits perfectly and with a total weight of under 15kg I can flip to carrying it on steps etc without strain. My slightly heavier Roland RD-64 also fits comfortably. Quality overall looks good and the internal height of 160mm and full-length pocket are a bonus. Of course I don't
know how durable the castors will be long-term, but they seem robust.
One oddity is a stitched-on tag stating dimensions of 1010 x 445 x 160, which are not those of the actual bag!
