I wish I could rate this camera -9999999999999999999999999999999. Actually what I really wish is to mound all of the Vivitar Vivicam 55 cameras up in a pile and BURN THEM. Anyway, I found this camera at Walmart thinking it should be good for the $20 price tag they were asking. When I first opened this wannabe camera I noticed the buttons were very cheap. More than half the pictures taken were either blurry and/or yellowed. Don't bother trying to create a video with this thing unless you like a still frame video. I brought it back after I did some research and found the Logitech C310 Webcam for several dollars more here on Amazon(which has HD!). This is the worst camera i have EVER used. Live and learn, and never buy anything made by Vivitar. Shop around and spend a few extra dollars for a better camera. If not, you get what you pay for.

My little boy is just getting interested in these blocks. They are too cute! He's learning to manipulate the block in his hands. The little things inside the blocks are adorable. Some spin, some twirl, some rock. A definate upgrade from the standard wooden blocks.

Ex Output:
Positive

This is by far the worst of all the Transformer movies. Every scene with Shia and his blowup girlfriend is a slap in the face to modern women. After watching for thirty minutes, I realized I had wasted enough of my time and stopped the film. If I had paid for this, I would have thrown a temper tantrum until I got a full refund.
