Continuous meters

Hello everyone!
My question is whether you know that continued glucose meters currently exist in the market;And what is your opinion about its advantages, and which is the best for you.
Another thing I also wanted to know is if you know continuous meters by non -invasive techniques, and heard about "clocks" that every so often give you the glucose measures you have, but I think they are in experimentation and that there is some commercialized in the USbut not in Spain;My question is whether you know any, if someone is, and what opinion is, it is recommended.
Thank you.

In this same section of "insulin pumps and new devices" there are several threads on continuous meters that I recommend you if you have not done so.At the moment those there are invasive.
