Consumer Opinion Institute vs InboxDollars

Backed by global market research company TNS, Consumer Opinion Institute has an extensive background in customer service and responds to any inquiries very quickly.

Most users report a very positive experience with missing points or other problems being handled quickly and politely.

This could almost be considered a positive, but it can be extremely difficult to join Consumer Opinion Institute. Their clients demand very specific information from particular demographics, so you kind of have to be lucky if you happen to fall into one of the groups being accepted.

It should also be noted that no one is getting rich from this program as you'll generally receive only about three surveys per month. However, you will receive this consistently, so you can depend on the supplemental income.

One downside with Inbox Dollars is that you will get a TON of offers. Be sure you have your separate email set up just for surveys for this one. Some of them can be a bit on the spammy side and you will definitely get paid.

Note that Inbox Dollars does offer you compensation for trying paid offers as well which can be a turn off for many. If you do sign up for one of these be sure to cancel after you sign up unless you like the service of course. We recommend just sticking to the free stuff to avoid potential problems.
