I recently purchased the beast blender and while I think the design is great, I was disappointed to find out that the blend vessels are made of plastic. I expected the lids or some other minor attachment to be plastic, but I didn't anticipate the main blend vessels to be plastic as well. It would be great if there was an all glass version of the product available. While BPA Free Tritan claims to be clean, there is more and more scientific evidence that it could potentially produce higher levels of estrogen than BPA.
