Depending on your location will be the biggest factor as to what your usage would be like and the best type to get.
In states with a lot of sunshine all year round many people actually sell or bank their excess electricity to the power companies. The same goes for areas with lots of wind.
The overall initial cost is fairly high and upkeep is a constant factor but in the long run they pay for themselves in 3 to 5 years on average.

What do you think? The too-good-to-be-true products which promise something like taking off...?

I fell for the car fan also.....Seems you had to NOT use it if there was going to be rain that day!! how dumb!!!..I sent it back with a very large note stating that they should stop carrying this product, that it should be taken off the market....etc.......at least I felt good writing and sending it in!! LOL

These so called 'inventors' may make some money, but not much if the firms sellling their junk have to keep making refunds!!!!!!! so maybe it's a '50/50' type of thing.........

As for taking ten years off your face, which product are you referring to? I am a retired makeup artist and really get a kick out of how women, and men, too, abuse their skin for years with too much sun, alcohol, etc., then expect a quick fix; well, 'there ain't none!!!"........but I"d like to know which one it is, and if you bought it?????? Thanks!!!
