I have an Away carry on (have used it a fair amount) and while it's not bad and the outer shell and wheels are probably pretty durable, the straps inside are glued to the plastic and one has now partially broken off (still works but doesn't cinch down to the bottom of the suitcase).

I have since also bought a carry on by Horizn Studios for european travel, which I actually find is much more sturdy and durable. It has had a lot less use than my Away, but overall build just feels stronger, while also having a few nice (albeit minor) design things - like the small handle on the top for carrying being on the opposite half of the suitcase as the extendable handle
