Review: Saves the prints - This sensor really saves prints. I tried to print some dragon using Silk PLA and I failed three times due to clogging. I decided to upgrade my printer and install this sensor and for now it paused my prints three times due to clogging but I was able to resume printing after clogging. So I'm continuing to print. Minor issue with sensor - you will need to mount them - I found the custom mount compatible with my print head (ender sprite pro) and printed them. P. S. The above is definitely a filament issue. I printed a lot without any clogging but glad to see I'm able to overcome filament clogging issue with this sensor.
Review: So much better than stock. - So much better than stock. I have these on two Neptune 4 Max, on which the stock extruder is prone to the blob of death. The sensors detect both runout and filament movement. The Klipper tweak is available on GitHub, the whole thing took two minutes.

### ⭐⭐⭐⭐⭐ So much better than stock.

So much better than stock. I have these on two Neptune 4 Max, on which the stock extruder is prone to the blob of death. The sensors detect both runout and filament movement. The Klipper tweak is available on GitHub, the whole thing took two minutes.

### ⭐ How are you supposed to feed filament through these!
*by D***E on July 3, 2025*

These things are terrible. I've got three of them, and NOTHING feeds through them easily. The design on the inside just sucks, it has a tiny hole that filament has to somehow make it through, but filament is curved, and being pushed around by the rollers inside this. You're supposed to hold the lever down with one hand, while trying to force filament in with the other. All three fail to feed constantly. Once you manage to get filament through them, it's fine, but I don't see how anyone can give these good reviews if they actually used them. I'll try and make new housings for them, maybe I can fix their poor design. If you can't do that, don't bother trying these.
