Works well, good features, some bugs but good customer experience

It's a rather expensive product, but they're probably the most feature extensive bike lights you can buy. Especially the signaling (blinker) function makes it worth it for me, although it's best used in combination with their blinker remote (and the sadle bracket for the rear lights), addin to the price. The overall experience is very user friendly: the pairing process (both between the lights as with your phone), the useage and setting the lights' modes on the app are all intuitive and fast.

I experienced some bugs with the app at some point, but they communicated a fix via email and it's clear they're working on it.

The most negative point for me was that one of the lights started acting up after trying to turn it off (by long pressing), a subsequent firmware update didn't go through properly (it never indicated it finished updating), and after a few more uses the light got bricked (or something): when connected to the charger, it showed the small green light indicating it's fully charger, but it couldn't be turned on anymore. After explainig the problem via email, I got send a new light free of charge within 2-3 weeks of my first email.

So overal I'm very satisfied with my purchase.

Superb device

But the charger is worse, because it always causes overheating of the Firefly. It works better by charching it with Apple Mac-Safe.

Great bike light and even great customer service

Can’t say enough good stuff about my lumos lights! One went out after 2 years, and they replaced it without any problems. I use them every day and they are awesome!
