Because I was also curious, I actually went through and linked all of the items I have received for Free so far.
Based on the prices I see today, I've received about $350 of goods for my reviews. I estimated it to be over $500 because at the time, the listed prices on some of them were really high.
The only thing I don't recommend are the silicone tongs you see below. The handles are silicone but the grabbers are smooth plastic and not very sturdy. It's good for picking up light weight items only. It won't grab heavy products or even spaghetti noodles. The only good things about those tongs is the spring and the lock. It's very sturdy. The rest, not so much.
My favorite product I've received so far has got to be that selfie stick. It's a bluetooth remote control so I can also use that as a remote for my iphone when I have to take group pictures. No more self timer apps and running to get to my spot.
The item I never leave home without is the life charge battery case. It's light weight and provides extra power when I need it. I'm sure the juicy pack will be 2nd in line. I'm still charging that up and have yet to use it.
