It's nothing fancy, but for 35 bucks, it's not bad at all.
-On the outside, the wheel piece looks pretty small but once you open it up, you'll see it holds plenty for a 2-4 day trip. It even expands about two inches, and it seems to be well put together so far (roller & handle work fine). It even has a small lock & two keys for the cautious traveler. If you're looking to go compact, this is what you want. Not too big or bulky at all.
-The small carry piece is about 3 to 4 inches wide with a nice strap & good number of compartments. It's perfect for under things & toiletries, as well as other odds & ends.
-The color choices could be better, in my opinion. I chose the green color, which all the negative reviewers refer to as "army green" to make it seem ugly. Not true. It's just a calm, subtle mossy green. I didn't want my luggage screaming "HEY EVERYONE, LOOK AT MEEEEEE!!!!", so I opted to skip on the mustard yellow, rave purple, & electric blue. Too loud for me, but whatever floats your boat. :D

All in all, it'll definitely serve its purpose & it would be hard to beat the price. The only thing I want to stress is that if you're going to be traveling any longer than about 4 days, then you might consider a full set with bigger components.
