The first set came with a wobbly wheel.  So I called Traveler's Choice and they offered to replace the entire set and didn't even require me to go through the pain of returning the original thank goodness.  It took a long time (several months) to get the replacement, but it did finally come and with no wobblyness. But the hard cases weren't quite as sturdy as I'd expected...actually, it's pretty flimsy compared to what you would expect for a "hard case" luggage set.  I wouldn't buy this particular set again, but I would buy another Traveler's Choice product.
