Title: Oster 6640 Blender
Product review: I had the same model for 20 years. Just last month it started to leak oil and wasn't chopping or mixing as well as it should. After 20 years it needed a rest so I went looking for a similar blender. I was pleased to find the same model is still being made, however now it is much lighter and easier to use. The jar is plastic now, the older one was a very heavy glass. I do prefer glass. This works very well. My only complaint is that when I use the chop, grind, whip and grate modes the darn thing moves and the lid pops up. I have to hold it down and still. Annoying, but not too bothersome considering how well it works for the price.
