Perfect replacement for my MK4

Installation was straightforward. The temperature stability is excellent, and my prints look just as good as they did with the original part. Highly recommended for anyone needing a spare.

Every Prusa owner should have one of these in their toolkit. The fit is precise, and the included sensors match the firmware expectations perfectly.

My old hotend was causing frequent clogs. This new kit resolved the issue immediately. Temperature readings are accurate and consistent throughout long prints.

Works well after calibration

Needed to run a PID calibration after installation, which is expected. Once calibrated, it holds temperature very well. Good product overall.

Good quality, fast shipping

The build quality feels solid. It took me about 15 minutes to swap it out on my Prusa XL. One star off because the wire shielding could be slightly more flexible, but it works perfectly fine.

Great value for money

Much cheaper than buying directly from the manufacturer but performs identically. I keep one of these as a backup now for every printer I own.
