Very poor. When connecting devices it just shows a percentage that ticks upward to 100% regardless of whether the device connected or not. Oh yeah the device near connects. Useless. Went through all troubleshooting. Also has no way to contact support. Update: Can I give this even less than 1 star. All I want to connect is one device just one and it was working. Now thanks to the smart life app update which I didn't want to do its all stopped working. Worthless.
