I'm flying from the US to Panama, and trying to bring things to make my kitchen in Panama work as well as my kitchen in the US does. That means bringing the things I find myself using a lot - and some of those things are a little heavy. My ticket allowed me to take two bags with up to 70 pounds each. My trusty ETEKCITY travel scale (from Amazon) told me I had loaded this roller bag to 68 pounds - as confirmed at the ticket counter. I could have stuffed a little more in, but who wants to push your luck at the ticket counter?So, the bag has great volume, just under the size limits, all of which is good. Here's the rub. There is no real frame to this bag, so the load makes it "slump", so unless you are a tall person with short arms, the bag wants to drag its belly over any bump. Also, since you are hanging onto the handle on the edge of the bag, it wants to bump your legs as you walk. It's OK for a short distance, but I had to cover a pretty good distance from the car to the ticket counter, and when I arrived from the baggage area to customs, and from there out to ground transportation - it's a LOT of work, trying to hold 68 pounds far enough away from your side so that you can walk, and hold it high enough so that it doesn't drag. It'll make you sweat - curse, and sweat some more!If the design had a stiffened post from the wheels to an extendable handle, it would be the best piece of luggage n the world. So, that's what I'm looking for now. I thought I'd found it, but until I travelled with this, I didn't really know what an improvement a few tweaks could make....
