I bought these. After two uses (the first being a french vanilla cake, and the second fudge brownies), they stained from the brownie batter and will not come clean. I figured these would be better quality, since they ARE kitchen aid.

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.

The material is thin thin thin which I expected from this kind of costume. The mask didn't really hold up for one halloween party and one night of trick or treating. The worst part was that the cape in the picture is big enough for the girl to hold with both hands but in reality it isn't that big at all. Also the velcro that holds the cape on didn't even hold up on Halloween night. Disappointing
