[EX Q]: This heater works really well. You set temp's to desired amount of temperature,its a lot like a big space heater. It will blow cold air into room very quickly.
[EX A]: Good Review

[EX Q]: This stylus isn't anything special, but also nothing particularly bad.
[EX A]: Good Review

[EX Q]: This product does not work very well at all. I have a 6 year old Sony camcorder. They should warn of this limitation. I also used to be able to use rechargeable AA batteries which was great. Why they discontinued that is beyond me. You need one type or another battery for the video option. Also, you can only shoot 1 hour video before your camera has exhausted the batteries. In other words, if it goes dead, all you've done when you switched power on is turned off your camera.
