CR Sprite Extruder Heater Block Kit Extra Thermistors High Temperature Pro 300℃, Ender 3 S1 Hotend Compatible with Ender 3 S1 Pro/Ender 3 S1

great upgrade for ender v2 easy upgrade that works great I printed a mount for it before I took my old hot end apart and it was really simple to wire in

This upgrade fixed the problem I was having and works great, definitely a good buy

Awesome product. Buying another one now

Tried multiple prints after install this and has horrible results. Took apart the whole printer to make sure everything was tight and level. Tightened nozzle, removed hot end and then put back on to make sure everything was right. Nothing worked. Then I replaced the nozzle with my old one which is the same size and it worked great.

This completely replaced and fixed my problem of a bad thermistor and gave me two extra replacements.

This does not fit my K1

See photo as it is installed in my modded S1 Pro. Works exactly as advertised. Installation isn't too bad if you're generally handy. The small screws can be a pain, but if you make sure everything else is tightened correctly you can even leave them out. Would buy again if my current one died, but I'm over 2000 hours with this one so far. Heats up fast, stays consistent throughout print. 5 stars.

I mainly bought this for the bi-metal heat break for my Ender 3 S1. I don't need the 300c capability but trying to buy just the bi-metal heat break did not cost much less than this kit. If I need to print at 300c Creality has a firmware update for it. The Ender 3 S1 and Ender 3 S1 Plus both have the crappy standard Creality PTFE pass through heat break which causes the PTFE tubing to sit on the print nozzle which melts it and causes all kinds of fun to trouble shoot. I highly recommend this for any S1/S1 Plus owner!
