Vitamix C-Series Variable Speed Blender Black (5200)

This is the best blender design I have ever used! I make mass gainer protein shakes every day, and on many other blenders from other companies, a hard biofilm would eventually form in between and underneath the blades. My last blender in particular had 4 blades joined by a bolt and washer and I would have to periodically go through all the effort to disassemble it to scrub the biofilm that got stuck in between the blades. The Vitamix 5200 has a single blade design, so there is nowhere for residual protein powder to get stuck and makes cleaning so simple and easy. The cap design is great too because it's a smooth cup design with no ridges, so protein shake residue can't get stuck in any folds. This was twice as expensive as the most expensive blender I owned previously, but the great warranty, great power, and ease of cleaning make this the best blender I have ever owned and justifies the price.

I have used these machines since 1998. Still happy about a new purchase of another great Vitamix.
