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 Kyle Smithlin

My Wife and I have had a Ninja Blender for about 7 Years Now that we've been using for shakes and smoothies for after the gym. Well over the years we have used it so much that the wear and tear of the blade has dulled and I had decided to get on Ebay and buy a new blade bottle top but after looking at prices on those I just decided to go ahead and get a new unit.My reasoning was it was only like $50 bucks more for a lower profile unit, and this blender comes with a 32oz shake bottle as well which is nice for as I make my smoothies bigger (80g of protein 3 times a day at the least doesn't come too easy). And the smaller 24oz cups were a bit more crowded with all that I put in them.Pros : Low Profile Unit Wide Mouth Cups and Size for Blending Auto Blending for Smoothies (which turns the unit on and off to let settle then back on a few times) Much Sharper Blades than my last unit I believe (might just be that my old ones were so dull!Cons : Only thing I have noticed is they still leak if you overfill them (which surprise I still do with a 32oz). None really other than user error.
