Why do you want notifications? I got one (also just to experience it) and found myself frantically trying to turn off the incessant notifications like a sick game of whack-a-mole until I realized it didn't offer the intrinsic value that my notification-less phone does.
You disable the notifications that you don't want to see on the watch.
So for me personally I only have phone calls, SMS/iMessages, and one or two other communication apps enabled to send notifications to my watch, plus score updates from baseball since I follow the sport.
Once you get it configured in a way that fits what you care about it works really well.
I have a Pebble Time Round, basically just for notifications. Most of the Apps are disabled for notifying on the watch. Text messages, BBC News Alerts, Find My Friend geofencing alerts and Podcast available are the only ones I have on.
Not having to pull out my phone while cooking, or cycling (my daughter alway seems to text me when cycling home from work) is very handy.
