My prior favorite suitcase finally gave up... unfortunately they don't last forever when they are bounced on luggage belts, thrown onto luggage carts, and squashed into airplane cargo holds.
This suitcase was a bit more expensive than some, but the prior reviews suggested it was well-made and well-designed.  It's now been on a 3 week trip to Singapore and back (6 airplanes, and traveling over 20,000 miles) and worked just beautifully.  It was checked luggage for this trip, and supplemented by a small daypack for the things I wanted to keep with me on the planes - a change of clothing, personal electronics and valuables.
This suitcase is smaller than the one it replaced, but is very well designed and held everything I would normally take.  Its size also means I'll have no trouble getting it into overhead bins when it's a carry-on.  And I love the 4 spinner wheels!  I've never had those before, and they are just fabulous.
I'm very glad I paid a bit extra to get this excellent suitcase...
