## Customer Reviews

### ⭐⭐⭐⭐⭐ A sound barrier that works
*by K***F on August 25, 2025*

Great product, easy to apply, sticks really well, works great

### ⭐⭐⭐⭐⭐ Absolute gamechanger!
*by J***M on July 3, 2025*

I'm one of those people who research for a week then buy the best product possible. Often times, if you research enough you can find one of those companies that is putting out an insane product without paying for the name. This is one of those products.I needed a solution for my new system in my car. I stumbled on an experiment from an independent rival company that tested the top brands. This 50 mill version was a slam dunk. Performed better than 90% of brands and even a ton with thicker products.I installed this in my whip and it definitely steps up to the plate. It does a fantastic job sticking to things and easy to put on in tight places. My car sounds like Bose QC35 headphones on a solo camping trip. It's a much different experience from my noisy old car. Did I mention that I have a moonroof and roof rails. Still quiet though.I can honestly say that, for the rest of my days driving future cars, one of the 1st things I will do is pull out all the interior and put in Canopus sound deadening.Save yourself the time. Add to cart.Coming from some random midwest dude... you're welcome!#cheers

### ⭐⭐⭐⭐⭐ Really good sound insulation. Lowered noise and vibration under the hood.
*by Z***O on September 7, 2024*

Really good sound deadening material for my Buick. There are several things about this I like that I liked.- It's made in the USA, which shows in the quality.- Speaking of quality, the butyl material has very good adhesion properties. My hood has some indents in it for the heat insulation to fit into and the material stuck and conformed to the indents.- I was able to use scissors to cut to shape. In most situations I had to use a knife on other brands. So easy to cut and install.- The roller I used did an excellent job. The foil was strong enough that the roller didn't rip the foil on top of it. I also had this issue with some other brands.All in all it does a very good job. The sound of the intake and loud injectors all went down significantly. Cruising on the highway also showed it lowered road noise from the front wheels. Even with the amount I used I still have 3 sheets left. Definitely a good buy.
