I had a brand new all metal Micro Swiss hot end that I bought right after Christmas but I didn't tighten the nozzle enough and ended up making quite a mess when one of my print jobs failed. I disassembled the hot end to clean it but found that I had stripped one of the screws in the heater block so I couldn't get the ceramic heater cylinder out. Luckily I was only able to buy a thermal block. Installing the thermal block was easy (after pulling a new heater barrel through the wiring harness and screwing it into the motherboard, but that's another review of the product). Prints great! I'm currently printing a Mandalorian helmet. Highly recommended.
