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?

I would like a smart band that I can take in the pool. Not water resistant. Something that can actually go in the pool with me.

Hi, I'd look at fitness trackers that specifically have a swim mode. Withings, Garmin, and Misfit all make waterproof fitness trackers that can go in the pool with you, and I know that Withings and Misfit models include swim tracking. I've personally owned a Garmin Vivofit 2 and wore it in the pool several times. Hope this helps!

I am wanting to buy something for my husband I that is a pedometer and has a heart beat rating. Not an over the top price though. Saw a Fitbit one that a nurse had tonight and I think it did only these two thigs, but I could have been wrong. Good advice welcome

Hi there, the Fitbit Flex does not include heart rate tracking. If you want heart rate tracking included with the wristband it's usually a little bit more expensive.

Here is an article comparing two heart rate tracking models:

You can also get some chest strap heart rate monitors (Polar has one) that can sync with a wristband, but it comes separately.
