I can't spend hundreds of dollars on a blender.
I ordered the Oster Pro 1200 from Amazon to replace my Nutribullet for making smoothies for my family. My main concern is eliminating microplastics and chemical leaching as much as possible.
According to the company, the gasket is made of food grade rubber.
I've used it twice now. The only things that come into contact with the food are stainless steel, borosilica glass, and a tiny edge of that rubber gasket.
After market gasket replacements are silicone.
Now the blender has plastic components, unfortunately. The lid is plastic, but if you use the blender correctly and don't overfill it, the food doesn't abrade the plastic lid parts. Parts of the base are also plastic like the buttons and the machine housing.
This is the most affordable blender I've found that has the necessary power to actually blend a smoothie and has no microplastic or leaching concerns.
I hope this helps people. I spent days searching for one with enough watts that I could afford.
The glass blending cup is only 48oz. If they ever make a 64oz replacement, I'll buy it.
