I know mine isn’t broken, but I will say, it is underwhelming, I have to try and light it up when it is dim, or I can’t even see it. The KBR will light it up somewhat, but it still has to be on top of it.
Basically, I feel like I will not use it much, as it is super hard to get to light up with my phone.
Edit: I did just install mine a few days ago, so maybe it is the swelling? This is just my current observation.
