drop in replacement. no issues. came in silver.

These work well on my Tevo Tornado. These are not supper tight but work. Make sure you put it on so the sock covers part of the Thermister. I was getting thermal limit error messages when I cut the sock to fit around the Thermister. Changed it and my printer works great now.

Cheap enough to change when switching my Ender over from long PETg print back to PLA. They work great.

I used to make little rubber parts. These are good quality.

Unlike some of the other Silicone Covers available, these were just like the originals. They fit and work just as good as the original cover that come with the printer.

Perfect fit for stock Ender3 V2.

These are nice socks but that are not as pictured. They cover more of the nozzle. Ended up returning them without issue and still looking for what is pictured.

These fit my Ender 2 Pro just fine. No issues getting them on or off. Great to have a few replacements standing by. I think the original ones have almost a thousand printing hours by the time I replace them and I only replaced because they are so cheap, I figured why not swap em out.

It does a fantastic job keeping things cool. I’m able to run PLA parts coolers almost touching the extruder.

Not much to say, standard heat sock. Seem to hold up pretty well to wear.
