Reviews, attributed to the product
"It disappears. I stopped noticing it after the second day, and the sleep breakdown is the only part of my morning routine I actually look at now."
"The camera is in the right place — nobody has asked me what I am wearing, which is the whole point. Battery gets me through a workday."
"Bought it for the tint control and stayed for the audio. Calls in the car are clear and I can still hear traffic."
