Can't remember which thread, could have even been an Apple Watch thread, but some people did recommend returning the product and see if you missed it. If you did, then buy it again,
I think that's more - if you're not 100% thrilled with it and uncertain, then return it.
You can always buy it again later if you change your mind or think it fit into your use after all.
Which makes sense.
Speaking of the Apple Watch - I had one at launch. After a few weeks it somewhat lost it's luster, so I returned it. A few months later, I switched jobs to something where the GPS navigation, alerts, and timers would of been very useful.
So I bought it again, and it turned out to be very useful.
