Little known product perfect for the snow - Must have!
2009-01-28It has been snowing quite a bit this winter and I decided to buy two of these for my girlfriend and two for myself. That way if we go somewhere we get one on the way there and one on the way back. Let me tell you, these things are great! My girlfriend loves them and everyone we have shown is amazed. A simple click of the button causes the liquid to crystalize as described and it hardens quite quickly and is warm (sometimes hot) instantly. They seem to stay good for about 30mins, sometimes more sometimes less but generally 30 on average.
For recharging I have found individually they take more than 10 mins to recharge (as stated in the description) but it is usually only a few minutes more. I tend to do two at a time and it takes maybe 20-25 mins which is still fine even though we use them every day.
The only con I can think of is that on really really cold days, sometimes you don't even need to click the button to activate. If you simply squeeze the plastic so that you're touching the button it will activate. That said it almost never accidently activates when not needed but it has once or twice.
Overall, brilliant product if you live in the cold!

Audio & Video Connections Guide
" For a list of all the ways technology has failed to improve the quality of life, please press three." - Alice Kahn
This quote is certainly applicable to consumer electronics. From the very first commercially produced radios to the latest in high-definition television technology, the manner in which the components used to deliver our news, music, movies and entertainment are interconnected seems to have escaped logic. For both the newcomer and the old hand alike, connecting equipment in the most efficient and effective manner can be a painful chore. It is hoped this article will improve your background knowledge concerning potential A/V system connection schemes and where each is most appropriate. The next time you find yourself in a "connectivity quandary" perhaps the ideas shared here will help you to quickly solve the riddle of which wire goes where and why!

VHS
The VHS format is the oldest type of camcorder. This type of video camcorder
is fast becoming outdated, because you can only play back
the video on a VHS VCR system. VHS
camcorders are not nearly as clear as digital
video camcorders that offer clear video with 540 lines of resolution,
VHS video cameras only offer 240 lines of resolution. They also weigh more
and are much more bulky, that dv camcorders. You can only find these video
camera used because their technology is now outdated.

camcorders come in a smaller size that the VHS camcorder models, but use
