Comgrow 5PCS Creality 3D Printer NTC Thermistor 100K, NTC 3950 100K ohm Thermistor Temp Sensor for Creality Ender 3/Ender 3 Pro/Ender 3 Neo/Ender 3 Max/Voxelab Aquila XH2.54-2P Connector (1.3m/51.1in)

Being new to 3D printers, I have no clue as to what is normal when it comes to parts. Not wanting to take chances on getting the wrong ones, I purchased these because the description specifically states it will work on the Ender 3 Neo and they’re from the same company as supplied the Ender printer I bought at Christmas. I even spent the extra $2.99 to get extra fast delivery.Alas, I found all 5 of the thermistors had glass bulbs which were .3mm larger than the one my Neo came with (1.91mm vs. 1.61mm) and wouldn’t fit into the hole the old one came out of, rendering them useless… or so I thought. I came across another review from someone with the same issue who said they resolved the problem by drilling the hole slightly larger. Finding I could get other thermistors built into a 3mm threaded bushing (going in the old screw hole), I figured I had nothing to lose by trying to drill the hole a little larger.TL;DR: a 5/64 drill bit is the perfect size (pretty much just cleaned out the hole) and I was able to position the print head in such a way that I was able to drill it out without taking everything apart. The thermistors fit perfectly now and I’m an hour into my print job; temperatures are holding steady. With any luck, it will last longer than the two months, the first one did before acting up.EDIT: I changed my rating from 3 to 5 stars. After more research, I determined the thermistors I received are probably a better quality (sized properly and not a distorted shape) than the one that was originally put in - and it was likely a thermal paste used on the old smaller one which was keeping the new ones from going in the hole. I did not install the new one with any paste and so far it’s working great; opinions differ on whether to use it or not.ALSO, Comgrow reached out after my initial review and offered a full refund which was a nice touch but refused. Perhaps, if I had reached out to them first, they would have suggested cleaning out the hole. A good learning experience nonetheless. I hope my experience helps someone else.

The 5PCS Creality 3D Printer NTC Thermistors have been a reliable addition to my 3D printing toolkit. They perform admirably and have some notable strengths.First and foremost, the compatibility with Creality 3D printers is a significant advantage. These thermistors seamlessly integrate with my printer, and I've experienced no issues with installation or calibration.In terms of accuracy, they hold up well. The 100K ohm resistance provides reliable temperature readings, ensuring consistent and precise printing results. I've noticed minimal fluctuations in temperature during prints.Durability is another area where these thermistors shine. They seem to be built to last, and I haven't encountered any issues with them over extended periods of use. This level of reliability is essential for uninterrupted printing projects.The inclusion of five thermistors in the package is a nice touch. It provides good value for the price, especially for users who tend to go through them over time.While these thermistors perform admirably, there is room for improvement in terms of documentation. Clearer instructions or information regarding recommended usage and troubleshooting would be beneficial, particularly for less experienced users.In summary, the 5PCS Creality 3D Printer NTC Thermistors have proven to be dependable and durable components for my 3D printing endeavors. They offer good value for the price and are compatible with Creality printers. While documentation could be improved, the overall performance warrants a solid four-star rating.

Great replacement

Hard to screw up something so simple, they work and are an easy replacement for the stock thermistor on my Ender 3 when it broke.

So for some reason the old thermistor had welded itself into the heating block. I tried to drill it out with no success, however I had the bright idea to just drill a new hole for the new thermistor and so I got a 1/16th drill bit and made a new hole, printer is now 76% done with a 48 hour print.

After buying a MULTI SET of (5) MK8 HEATING BLOCK/HEATING ELEMENTS/THERMISTORS, this set came with the most horrible thermistors, super thin and cheap wires that break immediately when trying to strip off the coating AWFUL!These are what you'd expect in a high-quality 3D Printer - MADE TO LAST!

The media could not be loaded. I don't have any issues with these thermistors.Replaced the one on my V2 Neo, been working great right away and the temperature has stayed consistent for 2 months now. I even temporarily put one on my Max Neo (even tho the description says it's not meant for it) and the temperature is fine. It's 1m long so it's too short for Max Neo.I bent the thermistor where the bulb is for easier feed. I didn't splice it, I used the whole wire and plugged it in. I even put the bulb in the hot end clean. Twist the screw till it stops. Don't over tighten it. The white residue is from boron thermal paste the factory uses to hold the thermistor in place.Thank you!

This is Stock Ender 3 Thermistor. The five pack is nice to have extra on hand because you will need it eventually. Wire length is perfect. A little trick is the tape the new connector to the old thermistor bulb end and pull the new one through to your board instead of trying to feed it all the way through. Then replace your zip ties and ready to go. Took me about 10 minutes to replace.
