### ⭐⭐⭐⭐⭐ Worked Well — Until It Didn’t
*by J***Y on June 22, 2025*

The media could not be loaded. I really liked this product when I first got it — it worked great and did exactly what I needed. It was reliable, easy to install, and I was genuinely impressed at first.After close to 3 weeks, the key wouldn’t turn and I took it off the cluster and it was burnt up which was a bit disappointing since I took good care of it.

### ⭐⭐⭐⭐ Did the trick
*by M***. on June 21, 2024*
