I really like the Polar m400 for the external HR monitor (H7) but also really want a watch/tracker that has a silent alarm mainly for the ability for it to wake me up in a light sleep cycle. Are there any other brands you recommend with same features as the m400 but with the silent alarm function?

What is the reason I should buy a Fitbit Blaze instead of the much cheaper brand that does the same fuctions

Generally speaking, the customer service is great with a Fitbit, and the app is excellently built and user-friendly.

I have the elegant i5 smartband but it's unreliable.. I'm looking for a similar reliable model. I'm not a fitness freak. I just want a step counter, sleep monitor and notifications of text messages, calls and wattsapp. I'm looking at Fitbit alta and garmin vivo2. What do you recommend?

A:

Of those two options, Alta has wireless notifications built in.
