My second band was sent back to MS last week and hopefully they'll send me a refund. I'm looking at the Fitbit Blaze and the Garmin Vivoactive HR which are currently at the same price which means the Vivoactive HR is the best choice. However, I wear a lot of suits and Vivoactive looks very bulky.
But the fact that it has built-in GPS and is swim-proof gives it the edge value-wise.
I sent my Band 2 in a little over 3 weeks ago. I chatted with support a few days ago. They said it passed inspection on Dec. 14, but they are out of inventory (in the US service center). They said it will take 6-8 weeks to make a decision and issue a refund check if they don't have any inventory in stock. I don't really know why it takes so much longer compared to 8-10 days if they are in stock.
Anyway, I purchased a Vivoactive HR last week. It was the built-in GPS that was the biggest selling point for me. Apparently, both Fitbit and Garmin are having issues with Windows 10 notifications because of the lack of GATT support.
I only receive notifications if the Garmin Connect app is open, which is the only time the phone connects via Bluetooth with the wearable. If the Garmin app is suspended in the background or closed, the phone disconnects from the wearable and no notifications will come through.
As for the bulkiness, I'd say the watch face it's comparable to the original Band, but slightly wider. It is raised about 1 cm on the back of my wrist, but because it is a standard digital watch strap, there is less bulk on the opposite side compared to the Band's clasp. It is pretty comfortable for me. I'm currently wearing a dress shirt, and the Vivoactive HR is covered by the cuff of my shirt, which I can easily push up to view.
