[EX Q]: 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.
[EX A]: Negative

[EX Q]: We had to buy a new lunchbox for our son after 2 months (a different brand, machine-washable) because this one is way too hard to clean. I have turned it completely inside out, scrubbed between all the cracks, and still food is stuck in the seams andthreads. It is very durable, but we can't get rid of the smell or stains with a reasonable amount of effort.
[EX A]: Negative

[EX Q]: These are only meant for use as temporary or guest bedding, but I've been in a situation where I am using this item daily as my bed for over a month now. I am a large person. It has held up beautifully. I add air maybe once every 7-10 days. The flocked top is great, holding sheets in place. It is so comfortable, my back and general body pain has improved dramatically since using it! I suspect that when my permanent bed arrives, this little bed will serve long and well as guest bedding.
[EX A]:
Positive
