### ⭐⭐⭐⭐⭐ It works
*by J***B on December 12, 2023*

Our Otoscope stopped working after a fall and replacing it was just not in the budget. I did some searching online and found that sometimes the bulb just goes out. For 14 bucks, it wasn't going to hurt to try. It came in very quickly and after we swapped out the bulb, it worked like a charm! I'm glad this part was so easy to track down and the install was a wiz. Now we are up and running in almost no time at all.
