I use this Oster blender for smoothies and it works great.  The container is a nice size, 6 cups, and made of shock-resistant glass. It is easy to clean and dishwasher safe. It includes a convenient 2-ounce filler cap that has built-in markings for easy measuring and pouring of ingredients. It is very easy to use, nothing fancy but durable, and definitely meets my needs. The box had 2 recipes for smoothies that I tried and are really good.
