It all depends on if you are looking more for money or for products to test. I stopped doing Bzzagent because I wasn't getting campaigns any more and there was too much emphasis on social media. I won't make fake accounts or spam my stuff with products.
I used to do a lot more survey sites but have gotten rid of the ones that weren't working for me, but it's all relative to what demographic group you are in. What works for me as a single, no child, employed full time homeowner, may not work for the married, parent of 2, renter. With that in mind I do the following -
mintvine.com - it's a survey site, you can cash out for paypal,
amazon, target and a few others. 1,000 points equals 10 bucks. It has a lot of survey's, but they do seem to have their needs met faster, so don't let them sit. It's 5 points for most when you don't qualify and sometimes a random 30 for keeping up the work. I had very good luck with this site during the spring and summer, it's slowed down but it may also be my time contraints.
crowdtap.com - this one is hit or miss each month because the stuff you do enters you into drawings for each month. There are some months where I don't win anything, but more often than not I win at least a $5 amazon card. I've also won $25
walmart and a $50 sephora. It's the site that I get the most products from, they are generally sample and shares. They want you to share the items with friends etc. This site tends toward social media, but you can skip posting on fb and twitter, you just don't get the points associated with those tasks. I can do 2-3 hours a month on this site, doing all of the questions there. The just redesigned the website.
bing.com - I search on my phone and computer to get my daily allotted points and then redeem either for a $5 starbucks or amazon gift card. It's easy since on the desktop you can click on related searches instead of typing new searches over and over. No products, but an easy way to get a gift card every month or so.
pineconeresearch.com - I've done this one for years and like it because you won't get the survey if you aren't qualified. There will be some that are shorter and are used to determine if you fit for other survey's though. As mentioned above, it's $3 per survey, though they have changed it to a points system and you can save up points for items and stuff. You have to cash out now when before it was automatically sent to your paypal.
e-rewards.com - this is the other one I occasionally get products from. They have a variety of gift cards and products you can redeem for. You won't qualify for all of the survey's on this one, but you do still get something small for them.
There's one or two other sites that I get survey's from once in a great while, but I can't remember what sites they are. The above are my main 5 along with swagbucks, which has it's own thread on here with great info.
Hope this helps!
