As with all electronics today, these bridge have aged out and are no longer available. That doesn't mean they don't work. I have a mixture of WEMO devices added onto over time. This bridge helped those "smooth out" and also allowed better connection to Google Home and some Apple-based apps. As for shipment - very fast.
WEMO lighting seems to be in a losing battle with Philips Hue. That said, if you have invested in the Wemo lighting ecosystem then these WEMO bulbs are perfection - reliable, easy to use, long lasting, and free from the reliability and set-up issues that come with "WEMO compatible" bulbs.
