The two free sample sites I would recommend to beginning reviewers are Smiley 360 and Influenster. Click on the tabs under this category to read more about each on their own.
Both are completely free to join, all they ask if that when they send you free products, you take the time to review them on various social networking sites, such as a blog (like this one), retailer reviews, Twitter, Facebook, Instagram, etc.
It's fairly simple and, I think, pretty fun!
Although you get these samples for free, you are required by law to give a disclaimer (that you received the products for free) but getting them free does not influence your judgement and that your review is still 100% honest and unbiased. If you click on my reviews tab you will see what that looks like :)!
Sometimes It takes a long time to get anything free from either site, and all I have to say about that is to be patient.
I have not received anything from either site in a while, but I try to stay up-to-date on surveys (as long as I am still having fun). I have occasionally taken a break from doing any surveys because I got too busy and I wasn't enjoying myself.
Some other free-to-join sites that don't require that much work are: PinchMe and BzzAgent. I've had a few issues with both, but they are still overall good sites.
PinchMe has products you can claim about once a month and it goes in your PinchMe box for that month. My boxes usually have around 4 sample size products in them (never have received a full size one...yet). My complaint with PinchMe is that the boxes take FOREVER to come and I've missed the deadline for some surveys simply because my box didn't come for over a month and a half. However, you just have to fill out simple surveys of the products in your box (around 10 questions, if that) to keep an active profile.

I haven't quite figured out Bzzagent, I've received two boxes from them and both contained one full-sized item. I don't know how I was selected for them, but I was so i'm not complaining! You can review it over an assortment of means and your reviews get judged to make sure they are quality. There is no minimum or maximum of sharing for these..I think you just have to do some. But like I said, haven't quite figured it out since I've only received two boxes.
*A lot of my more recent reviews have been from a collaboration with various company's, so they have not been through these sites unless I directly state it in the review*
If I discover any other gem websites online, I'll let you guys know ;)!
