I bought my last one (Bossa Nova carry-on) this summer, and have since been dragging it over cobblestones, escalators, transporting in trains, planes... it's holding up very well and I'm happy with the quality so far. I have 5 pieces (Salsa Deluxe & Bossa Nova lines) and none have given me issues in the past few years.

However, my collection ends here. I am unlikely to purchase any more Rimowa due to the double whammy of non-value added re-design and increase in price.
