What I expected and even better

Pretty aplication interface, practical and clear, and very convenient strap to wear!
There is a general interface that brings together all sleep away many steps .. and a special page for each mode, more detailed.
It's really perfect for me, I mattendais not as many functions, eg in the sleep mode can be seen in how long we sest asleep, how many times we sest woke up in the night, the light sleep and deep sleep time! it's really specific! Me more trouble sleeping and often wakes it really is! Perfect for me to understand my sleeping problems and show that to my doctor.
Jimaginais not for that price jaurais all this product and not very explicit and should mention all this, this is unfortunate for them that deserve BE mentioned, it would be the seller.
A good alternative to expensive brands! it was a good performance and pretty strap
