Curved end watch band for Vivoactive 5?

I just picked up a Vivoactive 5 and am enjoying it so far. This is my first smartwatch since trying the original Fitbit Versa way back when it was first released. 

I'm wondering if anyone has tried any of the "universal fit" rubber/silicone straps fro Amazon, AliExpress etc that are the "curved end" type that fit right against the rounded sides of the watch? If so, are there any that you can link or recommend? Much thanks!
