There are 3 things to know about this light.
The first thing to note is that there is no way to cycle to the strobe option if you choose not to use the remote. There is a button on the side of the light and it only allows you to cycle through the 3 brightness options. The MagicShine website does not mention this at all.
The second thing is that the light does not come with an adapter to attach it to your standard bike computer mount. Instead, it ships with an entire mount of its own. This isn't a dealbreaker by any means, but if you purchased it hoping to attach it straight onto your Garmin mount or whatever, you'll need to purchase a GoPro style adapter which wasn't obvious.
The last thing to keep in mind is that the battery life is not great. MagicShine's website says 2.5 hours on max brightness and I think that is questionable. I typically average a 2 hour + ride so I'm almost always riding on the lowest setting unless I'm on a section of a route where I would expect to see some bumps/debris. If I happen to forget to charge the light after a ride well I'm basically screwed the next night I try to go out.
All that being said it's a decent light and MagicShine does have other decent lights out there too. My rear light I'm very happy with.
It works great so far, i like that it has a remote so i can easily go to high beam and back to low beam and to flasher mode without having to take my hands off the bars. The battery seems to be holding up well even though its been sitting in the cold garage for a month, I've only had to charge it once.
