Review on Ninja SS151 TWISTi Blender DUO - 1600 WP Smoothie Maker & Nutrient Extractor, 5 Functions + SmartTORQUE, 34-Oz. Pitcher & (2) To-Go Cups, Gray by Richard Koh

I have bought at least four ninja machines in the past ten years for myself as well as gifts. The things I like about ninjas are the jars as they make them of heavy duty plastic that hold up and don't scar when using to grind grains. (Yes, I have ground wheat with my ninjas and they have done a wonderful job.) I love how sharp the blades are and how powerful the motor is. I wish I could brag about the sharp blades on this one but I cannot. The blades are not sharp. The edge of the blade is curled like a badly sharpened knife. It feels like the blade was reworked and whoever sharpened it didn't know when to stop so the sharpened edge curled. I spoke to the seller, and he assured me I would get the cost of a replacement blade returned to me. I won't need to hassle with sending the damaged blades back. This is why I buy Ninja products.
