I've been playing with my new Fitbit Vera2 and Alexa, This has no speaker just a microphone so unlike the apple watch it doesn't respond with a voice. That's ok I'm not sure I could get use to my wrist talking to me.
It still feels strange talking to my wrist. I love the reminders from Alexa which I get with a subtle vibration on my wrist (still getting use to that as well).
Like the echo tap this doesn't have the always listening ability of other Alexa devices. You press the button then speak the request, the response is displayed on the screen for you to read.
I've turned on & off my X10 devices with this and it works, just a little slower then my Dots .
I looked at different face displays for this (must be over 100) but I like the default one it comes with. So if the display isn't to your liking there are lots to choose from however not all are free.
There are also 100s of compatible apps for this but I'm happy with the Alexa, weather, text and phone messages that display. I'm not happy with my failing eye sight as I need glasses now to read these notifications. Since these are coming from my phone I can retrieve them on it which is easier to read without glasses.
Alexa on this requires the Alexa app on my phone and since I have no data plan Alexa capabilities are limited to when my phone is connected to Wi-Fi. However I like the fact that I don't have to carry my phone around the house for it to work, the BT range is very good. I had thought about getting a couple more Amazon Flex units but this eliminates the need for those.
