I will never buy a two wheel piece of luggage again. I just took the middle piece out of the country, using it for the first time. Four wheels are awesome. Head this thing in the right direction and - voila - no achy arms, no pain in the neck.
This kit has three pieces to it. They come packed one inside the other like the Russian dolls. The all have wheels but the small one only has two. No problemo cause it is so small. I was carrying some stuff and middle one did great.
This is the first hard cased luggage I have ever owned. I was apprehensive but it just made through 4 flights with no problems. I am hard on luggage and time will tell how it stands up, but I think I am going to be pleased. Heck, at this price it was a massive bargain.
