The downside is that these are made of cheap material and wear down relatively quickly, depending on your expectations. I had hoped my original purchase would’ve lasted at least another year or two, but instead its lifespan was July 2022 to January 2025. That’s not bad….but still.
Regardless, I got two and a half years out of the original. In that time, it only went through one and a half batteries (I had to replace the battery once, and the replacement was still at least halfway charged).
And in that time, it worked great. Once in a while it wouldn’t respond to Siri or even pressing the shortcut manually, but in all of those cases I could simply open the Switchbot app and activate it from there. There’s also a good chance in most of those instances, it wasn’t a problem with the product, but with my WiFi or something.
So, if you don’t mind spending the $25-$30 to replace it every 2-3 years, it’s great. Personally I think the cost is worth it.
