These contacts are great! They last two weeks per pair (but will still work fine if you leave them in a little longer). They also are very comfortable. I've only had discomfort on days when I fall asleep with them in, which I've experienced with every other type of contact lenses I have tried. But all other times they truly do feel like you're not wearing them at all. They are also fairly inexpensive compared to others I've used.
I have noticed, however, that they are much more difficult to handle than other brands of contacts. They will fold or curl up very easily, and it is often quite a challenge to get them back the way they should be. This is especially true when you are using a new pair for the first time.
