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 daughter loves her blocks. She will get them all out and look at each one until she finds her favorite. She likes to shake them and see what each one does. These are cute little blocks that have hours of imaginative playtime inside. They also have blunt corners, so no sharp edges like wood blocks for the safety of smaller children. The fact that they have the letters of the alphabet and a corresponding object inside makes them a great learning tool even for older tots. We have really enjoyed these and recommend them to our friends.

The music plays just fine but the on screen picture is horrible. The picture is blurry and it looks like graphics form the 60's.
