I purchased this for a weekend trip so I could avoid checking a bag (isn't that what we're all shooting for these days?).  Here are the pros and cons:

Pros:

1) The bag is very roomy, with two outside zipper pockets.

2) It opens easily with an all-around zipper, which makes packing a breeze.

3) Wheels are slightly recessed, so they don't cause problems if you want to set the bag down.

4) Handle is easily accessed by pushing a button and pulling -- it's just as easily retracted.  This makes the wheel feature very simple to use.

5) The bag is lightweight and easy to carry (for those times when carrying is preferable to wheeling).

6) It has a second all-around zipper which enables you to enlarge the bag (great for return trips, when you always seem to have more than you brought with you!).

7) It seems well-made and sturdy.  I've only used it once so far, but so far so good.

Cons:

1) The bag will not meet airline carry-on regulations when it's been extended, so be aware of that.  The size is perfect without the extension, but if you need the extra size you will probably have to check the bag.

2) The little tote bag that comes with the set isn't really big enough to be of much use.  It's about the size of a large women's handbag, which means that's about as much as it will hold.  It's more of a "bonus" than a bag you'll actually use.

Overall, nice set.  If you're looking for an inexpensive bag, this is a good choice.
