Are there any sites similar to Serpclix?

I really like Serpclix because it basically gives me a notification while I am on my PC anyway and the effort to complete an order is like 3-5 seconds so it doesn't distract from what I am doing.

The last two months however the amount of orders has been steadily decreasing and i didn't even feel like there were enough before that.

So are there any other sites like this? All the other CPR boost type sites don't seem to use real people for the clicks
