I was annoyed at the built in LED on my P1S. It just wasn't bright enough for the camera or when I had to get into my printer for maintenance. I wasn't sure I was tech savvy enough to install this but I decided to take a chance. The instructions were easy to follow and accurate. Now all my timelapse look better and when I changed out my extruder gear for a hardened steel version and swapped my nozzle out I could actually see without trying to hold a flashlight in my teeth. I set the LED up to act like the H2D so I get color updates about the process that is running or if there was a problem. This purchase turned out to be easy in every way.
