Query: Would get five, but the noise, the noise

This is a great blender. Very solidly built, very easy to use, very effective. BUT it is loud. With the jar off, the motor does not make that much noise, but the with the jar on, it is almost deafening -- and high-pitched. Not ear-piercing but enough to make me want to hold my ears. I think two things cause this. One, the all-metal body. Great for durability, but the metal just transmits the noise. Second, if you look at the enlarged picture, you'll see that there's a silvery collar at the base of the jar, lifted a bit off the body of the blender. I think that this just allows sound to escape. Oster could have done something to baffle or muffle the noise.Still, it is an excellent blender -- if you can live with the noise.
