Took this to a 2 week Europe trip - 7 flights in 10 days (plus one train trip). The 25" size is perfect, not too big to carry around (a lot) but still enough capacity for two week worth of stuff. I have to admit though that 2 weeks is pushing the limit a little for a business travel, I think this Samsonite would be best for about 8-10 days travel max.
The wheels are super smooth and the blue color is easy to spot. Zipper quality seems good but will have to tell over time. The two front pockets are super convenient and overall the design of this product, both external and internal, is straight to the point. Also, there are very robust handles on the top, side and bottom. A bottom handle is very convenient and some other luggage don't have them. There a place to put a business card for identification too.
Inside, there are two zippered storage pockets, one mesh and one plastic - very useful. Otherwise, it's just one big space for packing which is great.
I highly recommend this luggage. It's durable, looks nice and very practical. My previous experience with Samsonite was always good, I have two other pieces of luggage for over 20 years now and they keep going strong, I hope this one will last a long time too.
