Just got back from my first trip with this bag and it worked wonderfully.  I'll never have a non-spinner bag again, it's so much easier going down the aisle.  Fits in the overhead bit without a problem and is LIGHT but still durable.  I took about 6 plane rides and it still looks great, did not get beat up at all.  Compartments lay out in a sensible way, and the handle works securely and locks out and stows with a solid click.  We are very pleased with this bag.
