Some airport bag cruncher has recently managed to crack my trusty Rimowa polycarbonate cabin trolley, which was checked luggage. So I'm going to try some Gorilla epoxy resin and aluminium tape to effect a repair. I'm not worried about how it'll look, just that it will fix the cracks...
Nowadays I try to use a cheaper Lufthansa cabin trolley from their 'Holiday Collection 2.0' range. About one-fifth of the cost of the absurdly overpriced Rimowa. Their prices seem MUCH higher now than when I bought my luggage...
