For around $230, there is really nothing to complain about. It has almost the same optical quality as the twice expensive 28-135 IS. If you do some google, you may find it compares very nicely with the much more expensive EF 24-105 f/4 IS. It is not as good, but very close. The optical difference, if any, will only show itself with 100% crop and pixel peeping.
The only weak point I observed so far is that it is a little soft wide open (3.5) at 28. However, if you stop down a little bit, e.g., 4.5 or 5.6, it becomes very good.
I roughly compare it against tamron 17-35 2.8-4 (model# A05, which is known to be a sharp lens) at 28. As I mentioned before, tamron beats this lens if wide open (3.5). But when stopped down to around 5.0, there is no difference (in fact, canon may even be a little better in terms of color & contrast).
I tend to use this lens mostly outside with aperture 5.6 or smaller. I used it for some portaits, as well as travel photoes. For this purpose, it does its job perfectly.
I am debating to give it a 4 star or 5 star (due to the soft issue wide open at f3.5). But considering its price, I am inclined to give it a 5 star.
