This bag weighs exactly 10pounds and 2 ounces empty.  Two pounds lighter than my other two bags that are of the same size.  The maneuverability is fantastic.  The material quality is good and the telescoping handle seems quite sturdy.  I am very pleased with the purchase and it will soon undergo its first travel test of a 12 hour flight.  I expect it to fare well.  Travelpro has always been a reliable company.  I am still using my bags that I purchased 20 years ago!.  I had a problem with a zipper once, and they immediately fixed it.  Just wish that the bag was made in the U.S.A. instead of China.  It is impossible to find USA made luggage anymore.

march 31, 2015 update.  I have owned this for 1 year and 5 months.  In that time I have used the bag maybe 6 times.  The quality is NOT up to the standards of my older travelpro luggage.  The stiching on the exterior trim came unstiched (after the first trip) and the trim fell off.  This was not a problem, since the trim served no purpose.  One of the wheels became misaligned (after the 4th trip)  making it difficult to wheel the luggage.  One of the  zippers on the interior mesh (after the 5th trip)  in the top of the bag came off.  Again not a huge issue, since there are two zippers on the mesh pocket.  BUT THE WORST is the two aluminum bars that run up the back of the bag severed in the exact same spot, so there is no longer support in the back of the bag (after the 6th trip). I put some cardboard in the back of the suitcase to try and give it some sort of stability.  I am waiting to hear from Travelpro about all these problems, given that the bag is supposedly guaranteed against poor workmanship.  I will update this later.
