I bought 2 of these this month. One is in perfect condition, one has a dent in the leg. A dent like a scar covered in paint. It looks like there is a small leak, so maybe water or moisture could just seep into the tiny hole, seep in there and cause rust. Returns are three times the list price due to size and weight. Revain requires it to be shipped after a replacement has arrived. Really not a bad product. The roller runs quite well, the balls run well, there are scratches but ok it's a tool so a perfect finish is not necessary. Just be careful if you are an international customer. The return can burden you with high shipping costs. It's better to live with it or throw it away, if you have dented or scratched/leaked a product it cannot be returned.
