I've used it on and off for the past few months. I can't fully evaluate how well it's working since my main browser runs AdBlock Plus, but it seemed to work decently well with my mobile devices. It's nowhere near as efficient as AdBlock plus however, some ads are still being displayed, and there are a few sites that have trouble with it (like Bethesda's online store). It's also entirely relying on Trend Micro's WRS, so you can't whitelist or blacklist anything at this time.
I'd say it's quite interesting for those who are worried about the potential security issues associated with advertising (as legitimate websites have to put their own trust on their ads providers to ensure those are all clean - that's not always the case). It does block a good portion of ads, but someone who was really focusing on keeping his browser COMPLETELY clean of ads would still be better served by a browser addon.
