BTT Smart Filament Runout Sensor (SFS) V2.0

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.

I upgraded from the V1 and this one is a nice upgrade.

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
