Now the Shine2 is out it's bigger (it's 30.5mm across and 8mm height) and comes in matt black (carbon back as Misfit describe it) and rose gold. It's also 50m water resistant. The original Shine had 12 white LEDs around the edge and the have been upgraded to RGB LEDs, there's also a 'buzzer' inside that can notify you of various things. The battery is still a CR2032 which should last for around 6 months and Bluetooth is now 4.1 which allows for faster data transfers.
The Shine2 can now wake you up by its buzzer (you set the time in the app), the original Shine had the smart alarm feature, but you'd need the phone by your side. It can now also notify you of calls and texts.
The strap and clip unfortunately don't feel as well made as the smaller ones with the original Shine, but then there'll probably be a slew of new accessories for you to spend more money with Misfit.
Having used the Shine2 for a day, sync'ing definitely seems faster, though you definitely notice the size increase.
Still a very pretty wearable compared to most.
It retails for $99.99 from the Misfit Store (they do ship to the UK using DHL so add shipping costs and import duties/VAT).
