Sound size: The noise is very loud. Listen to the video yourself! This store doesn't have any reputation. Send the address before buying. They said they can install it and buy it with confidence! After purchasing, I urged again and again. I waited at home for a few days and told me that it was "beyond the scope" and I had to install it myself.I have endured all this. Listen to the noise of this machine!It's useless to buy it. Neighbors complain!What a nuisance!!
