There are many sites on the web with reviews of gadgets of all sorts. I don’t propose to compete with them, since I’m certainly not a dedicated "gadgeteer." But I figure that an occasional post on some device that I find interesting or useful can do no harm.
One week ago, I didn’t know that devices like the Sodastream home soda maker existed. I read about it in an article in the NY Times, on how to save money and reduce waste. I did some "homework" (meaning web searches) and decided to purchase one.
