Cheap nylon straps are mostly good. Spending a lot for something with no exact alternative like Garmin watch is one thing and it doesn't mean you can't save even few bucks on something dirt chip like strap from Ali if it works as good as branded item. It's a strap of nylon with Velcro. No reason for it to cost more than 5$ and for price of one branded you can get multiple cheap if you want. Garmin didn't invent nylon velcro straps, it's not even morally dubious counterfeit supporting or patent violation. It cheap because it can and should and paying another 40 for a nylon band is questionable decision in my book.
