We love having a new blender, this Ninja Twisti High Speed Blender is a perfect fit for our household. As it has several options for each of us to use to our hearts content. The lid is amazing as we don't need to worry as much when using it, it will not pop off! It has this locking feature that works well with our ice and shake making recipes. The different size cups come in handy when we need a simple coffee drink or when we need to make a quick recipe. Easy to clean and use.
