This is my first Tumi.  I had used a Samsonite for many years - the Tumi is better in many ways.  It is sturdier, the zips are smoother, there is a separate suit compartment, the styling is nicer.  They even gave a tumi zip lock bag for toiletries, which was a nice touch.  The handle and wheels are both well constructed.  Of course, it is also more expensive but worth the premium, especially with the recent 20% discounts.  Very pleased with it and looking forward to trying it on my next trip!

Just back from a three day trip with the tumi. A real pleasure to use. Everything about the build is solid and smooth. It never threatens to topple even when fully stuffed. It is pleasing to the eye too . My one small gripe is insufficient pockets inside the main compartment. There are plenty outside but only the main can be locked.  I'm not a big fan of travel but this tumi makes me almost look forward to my next trip!

Btw, it's nice to see that this product is no longer discounted!

Update 22 Mar 2013
Just back from a 5 day long trip in HK - when you're bloody tired and can't wait to get home, you just don't want to deal with luggage problems.  That's where this Tumi excels:  the wheels are smooth, the bag doesn't fall over no matter how badly I pack it, it looks good and feels good.  Worth every cent and more.
