So far so good. I got this luggage set the other day and everything seems great. It's hard to give a good review without using them a few times first. But after I use the luggage a few times I'll up date my review in a coupon months.  From just looking at the luggage and feeling them, they seem very strong and durable. The wheels seem great, they spin around so easily and smooth. I like the handles, they feel pretty strong and look great.
One thing to point out is that they call this luggage brown, it's not very brown looking, it's more like a gray-ish color. I think it looks pretty good, but just to note, it is a little different than the picture.
I do wish there were more exterior pockets, but they do have the nice big pocket on the front of them, and the inside of the luggage has pretty good organizers.
All in all I'm pretty happy with this luggage as of right now and I would recommend it
