CANOPUS Professional Sound Deadening Mat for Cars, 50 mil 10 sqft, Butyl Sound Deadener Mat, Audio Car Sound Dampening Material for Car Trunk, Door, Floor and Ceiling, Black

Excellent product

Does the job. Good quality adhesive

Seems to be a good product and he’s very sticky and fits well

Bought to mod a Keychron mechanical keyboard. Very good at reducing ping from the aluminium chassis. For my needs, this was a large pack - could easily to 4 or 5 keyboards with this, depending on layout. Very easy to apply. As suggested when you get this, buy a roller to smooth this down. Would buy again if I needed more, which I'm not likely to for a while.

Seemed good quality, unfortunately the product needed to go under the main carpet on car floor which was stuck down therefore I couldn’t use so had to return but no reflection on the product

[Butyl Deadener vs 3D Printer] I applied 10sq ft of the sound deadening to my Bambu Lab P1S. I don't understand how this material works exactly, but basically whatever plastic piece I applied the Deadener too went from 'loud rattle-y' to 'quiet thud-y'. The sound is definitely MUCH better, like 50% of the old volume. Most of the forum posts and examples online only applied the Deadener to the inside walls, but I found by far the biggest difference came from applying small bits of mat directly to the Hot End and Extruder. Absolutely huge difference just by adding tiny chunks of Deadener to the casing. I was worried that I needed to cover the entirety of every single surface but it seems to be 90% effective even if you can only cover a small chunk of the parts. I was also worried about the weight impacting the printer and causing it to skip steps or something, but nah, it can still to 20,000 mm/s^2 acceleration just fine and much more chilled out sound. TLDR: It turns any 'rattle' sounds into 'gentle thud' sounds for a fast 3D printer. It's absolutely worth it, but it's not quite enough to let you sleep in the same room as your printer.

Definitely recommend, super easy to install (with a roller) and make a surprisingly big difference to my ragtop mx5. I’d mainly focus on doors and rear wheel arches which you can heavily cover with the 10 sheets. Makes the interior quieter and boosts sound quality.

I i bought these for my transit motorhome , it is pricy , but its great quality and does what it says its faultless , and will buy more in the future
