These metal bands are exactly what I expected (having used some on Fitbit Charge 2) for use with my new Fitbit Sense device. They're as good as the best Metal+Mag bands I've ever bought. Keep in mind that the "big" band is about 0.75 inches shorter than the long metal bands found on other Fitbit devices. However, these "big" straps work quite well on my large wrist.
