BTT Smart Filament Runout Sensor (SFS) V2.0

Nice sensor

I only gave it 4 stars due to the little resistance it puts on the filament. However, it is a very sleek design and should work great. I have been to lazy to mount and configure mine properly. Ended up removing it until I can install and configure better.

Works great

This is a good improvement on the previous version and works pretty well. Haven't had any false negatives since installing and getting configured correctly

A must have

Great little package with a lot of headache and heartache saving abilities. Highly recommended for everyone to have one, especially in this kit.
