Good quality, slight odor initially

The build quality is excellent and it handles high temps well. There was a slight rubber smell during the first few heats, but it dissipated quickly. Overall a solid accessory.

Must-have for PLA and PETG too

Even though I mostly print PLA, this helps maintain consistent nozzle temps in my drafty garage workshop. My print quality has improved slightly since installing it.

Great value for the price

Does exactly what it says. Keeps the heat in the hotend. Only giving 4 stars because I wish it came in a two-pack, but otherwise very satisfied.

Essential upgrade for consistent prints

This silicone sleeve made a noticeable difference in my ABS prints. The temperature stability is much better, and I no longer get layer separation issues. Highly recommended for anyone printing engineering materials.

Durable and effective

I've been using this for three months now with daily printing cycles. No signs of wear or degradation. It definitely reduces the load on the part cooling fan.
