I purchased this 3 piece set of Rockland Melbourne spinner luggage January 29, 2016. I used it once. This is the largest piece of the set, it is now unusable. This is just from one flight from the US to Europe (I am stationed overseas). It is supposed to have a 3 year warranty but I can't find a webpage or contact information for Rockland. It makes me wonder if it is counterfeit. I have had a previous set of Rockland (different model) for 3 years before getting this set. My previous set has traveled to Africa from the US twice, from Africa to Europe four times, US to the Bahamas and back, Serbia to South Korea and back twice, Serbia to Budapest twice, Serbia throughout Romania once (dragged over many cobblestones), Serbia to Italy (again lots of cobblestone draggage and hauling on and off trains, Serbia to the UK and back, Serbia to France and back, Serbia to Turkey and back, Serbia to Greece and back. It's only got some scratches. I bought this set for my 8 year old son and on one flight back to Europe this happens. It wasn't even very full, he's tiny, his clothes don't take up much space. The giant Kylo ren figure took up most of it which doesn't weigh much so it's not like it was overloaded. In the pictures you can see where the corner has completely split (no longer water proof), there's a crack going all the way through the plastic that is over a foot long in total.
