Just be very careful with regenerating this stuff.
I have been using it for awhile, and it seems to work better than GAC, but that is a totally subjective observation. I have not attempted to regenerate it yet, but people have had problems, as evidenced by doing some online research. The old instructions were incomplete, or incorrect (I can't remember which), and some people nuked their system. If you go on the Seachem forum, they have updated instructions for the regeneration procedure. I don't know if there is any way you can tell if you have the updated instructions with the product you've purchased or not.
If I remember correctly, the only update was that there was more rinsing recommended.
