At US$120, it's not cheap; and it probably has the same issue as I have with my US$13 Fosmon - needs to be re-paired periodically, even if the power hasn't been out:

UPDATE: After making this post, I decided to reach out to the Amazon Seller for the Fosmon unit I purchased in March of 2019 (5 years ago) to ask about a replacement since they have a "Limited Lifetime Warranty:" I sent my message via Amazon at 9:42am, received a reply at 10:18am asking for my contact info so they can send a replacement; I didn't see their message until 10:35am, sent them my info at 10:38am and just received (10:45am) their acknowledge meant that a replacement will be on it's way. Granted it's a one-time replacement, but I'm definitely impressed: although Milwaukee has a 3-year warranty on their switch, and I could buy (US$18) a 2-year HD warranty to take it to 5 years total, after 5 years & one month I'd be out of luck.
