This carry on luggage is good for the price you pay for it. If you travel a lot I would buy a better quality carry on. I have only used it one time with no problems except one. When you extend the handle to full length and drag the carry on behind you the bottom of the carry on drags some on the ground.  If you tilt the carry on at maybe a 45 degree angle and use the 2 back wheels the bottom of the carry on can drag just a little bit.  The wheels should have been 1/4 bigger so solve this issue. I just use the 4 wheels to drag it around the airports.  The 4 wheels work good.

The outside dimensions of this carry on are almost perfect. Airlines measure the outside dimensions . The outside dimensions are 21x14x9 . Check your airline what is the maximum size allowed. They are all different.

I'm happy with this purchases I made. It was a good price and I don't travel allot.
