Restored my printer
My previous heater block failed after a year. This replacement brought my A1 back to life. Heating is consistent.

Solid upgrade
Works as expected. The silicone shield definitely helps with cooling fan efficiency around the hot end.

Good quality but tight
The heater block is genuine and works well. The silicone cover was a bit tight to put on initially but stretched to fit.
