Thanks for this post. I should probably just wait for the review you promised, but the following things are of interest to me; maybe you can include them:

Are you wearing it all the time, or just for exercising?

Does it beep or make noise? (Is it possible to turn this off?)

Are you using it together with an app? Which one? Does it work well, or is there a delay or gaps in the data transfer?

Have you had any experience with water? (Swimming!?)

How often do you have to recharge it?

Is the only difference between the "alpha" and the "link" the display? Why did you choose the alpha?

Thank you for sharing your experience...the possibility for accurate monitoring without a chest strap is really exciting!
