I've never received two thermistors in the kits I purchased before, but they look really good. **Q: Is this thing a replacement for the Sprite extruder pro kit?** A: I think this is an upgraded version of the heating block that comes with the Sprite Extruder Pro kit. It has a bi-metal thermal barrier made of titanium and copper. **Q: What's the process for replacing it after I receive it?** A: Hey, check this out. The video has detailed installation steps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to install *by M***L on April 29, 2025* I have no idea what the nozzle size is but it’s a great product. Any help on this would be great! ### ⭐⭐⭐⭐⭐ Easy install on my sprite pro and 40 seconds to 240c! *by T***N on May 17, 2023* The ceramic hotend is a bit lacking on install instructions but easy to do. Removing the original sprite pro heat break and heater block required loosening one heatsink hex set screw and the two long screws holding the heater block onto the heatsink. I found that the original heat break due to the set screw dimpling didn’t want to pull out of the heatsink. So I just used a thin hex wrench thru the top of the extruder while pushing on the loading tab to push the heat break out. Worked and no damage. I then inserted the new hotend hear break into the heatsink making the bottom of the silo on boot even with the edge of the slanted fan bracket. This put the tip of the nozzle out har enough to have several mm of distance from the fan bracket and bed when printing. Easy enough to readjust if more clearance is wanted. I want as much of the copper heat break in the heatsink as possible. The new ceramic heater is 60 watts vs the normal 40w and does it heat fast. 40 or less seconds from room temperature to 240c and no pid recalibration needed and no thermal runaway triggered. I still did a new pid test anyway. I then set a new z offset and some test prints and DONE.For me it was a easy upgrade and so far great.Being so new I’m hoping to see spare nozzles available soon. Based on my other Creality hotend upgrades, nozzles and thermistors take a while to be available. For now printing pla and petg I should get many months of printing with what I have.I would buy again based on how it’s all working and ease of installing non my sprite pro (sprite also should be). ### ⭐⭐⭐⭐⭐ Great deal *by B***H on January 3, 2025* Fit perfect, and the extra parts are a good bonus. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/516336741-cr-sprite-extruder-heater-block-kit-extra-thermistors-high-temperature](https://www.desertcart.com.ar/products/516336741-cr-sprite-extruder-heater-block-kit-extra-thermistors-high-temperature) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-08-16*
