The Microsoft Band 2 was initially launched in 2015 and followed the original Microsoft Band, a device. We have a Band 1 and have been using it a lot. We bought the original band when it was knocked down in price to $50 and have to admit it was a jolly good price.
This price cut appears to be a sale and not a permanent, although we think that the $250 price was far too much for what the band can do. The deal seems to be available via Microsoft’s online store or Best Buy. Amazon is pricing the device over $200.
The Band 2 has a couple of features which the Band 1 lacked. One of them was a UV warning and the other was monitoring what height you are on. It would be difficult for me to justify both as I don’t do outdoor running and don’t really care about details of how many stairs I have climbed. The Band 2 is a bit more curveed and so fits on the wrist better. However the Band 1 &2 are good clear and simple watches and if you can pick one up cheap they are well worth it.
