A task is 20 minutes, if it takes longer they ask you to use more than one credit on a single task. And there was one task so far that took so long I ended up doing it myself (they refunded my credit for that one). But overall it has been decent. I haven't tried others yet.

I picked them because their minimum fee is reasonable. As it is I have trouble using all five tasks they give you. (it rolls over to the next month)

For example, the last thing I had them do was to call the landfill and schedule my trash bin to be replaced because the lid broke and put it on my calendar. It is a pain in the neck thing (they don't always pick up the phone... you have to wait on hold... etc) so the assistant probably saved me a lot of aggravation.

They have an affiliate link but it uses my real name and this is an anonymous account so no affiliate referral for me :)
