I was impressed by the material of this blender. The container is made of a very thick and heavy glass. The Oster blender was very easy to set up and the settings are easy to understand. It blended my fruit smoothie perfectly and liquified the fruit very well. There were no pieces left. I found that if you’re starting with very big pieces, you can start with the lower settings first and then proceed to liquify. Also, it’s very powerful and can be used for an array of things. The only thing I didn’t like about this blender is that it’s quite noisy. Didn’t really bother me, but the others around me complained a bit :). Luckily, the blender does work pretty fast.
