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.

Q: This product requires a stereo player in which the balance is turned totally to the left. Most auto systems have that capability. However if you have Dolby or SurroundSound, it can be difficult (and maybe impossible) to play the cassette without hearing two recordings at the same time. Unfortunately neither the packaging nor the website will warn you of the problem. You therefore should think before buying. Once you have opened the packaging you may be unable to return the product.

Q: My husband and I were unable to find any classes in our area that would work for us, so we purchased this DVD. We found it very helpful! I loved that I could go back to it and watch certain parts over again to refresh my memory. If we had gone to a class, I wouldn't have had that luxury. Once I went into labor, I knew exactly what to do and I was able to make it without any drugs. The nurses at the hospital were all asking me if I had gone to a class and I told them about the DVD. They said it must have been good because I did everything perfectly. I would highly recommend this DVD!
