2.0 out of 5 stars Cheap, weak blender, March 19, 2009

This review is from: Oster 6640 10-Speed Blender with Plastic Jar (Kitchen)

I just bought this blender last week and have made about 5 smoothies with it. For smoothies, I use frozen fruit, protein powder and rice milk. I let the frozen fruit sit in the rice milk for 5 minutes to start thawing out the fruit. Still, this POS blender cannot chop the fruit. The motor revs and revs and you can smell the little motor toiling away. Only the fruit at the very very bottom gets blended. I have to stop and stir and blend again. I wonder how long this motor will last as it strain to the verge of overheating.

I thought that $300 for a high quality blender was too much. I thought that if this one wore out and broke after a year, I would just buy another. That was a good theory provided that the blender could easily make a smoothie. I guess this would be good for soups but I am not even going to go there. I am going to return this ASAP.

If you do a lot of cooking or expect to blend ice or frozen fruit, keep looking for another blender. Trust me.

Great blender. I used to make smoothies with it all the time until we moved to France and had to sell it (volt converter costs as much as the blender itself...) Chops frozen fruit real well too. Try plain yoghurt + frozen raspberries + canned peaches + ice cubes + honey for a healthy but tasty snack!

I see this blender is hit or miss based on others' reviews. However, I have to give it 5 stars. This blender replaced a more expensive Black & Decker blender that gave up the ghost after no more than a year or two. This Osterizer I've been using for several years, and quite frequently. For example, I'm back on a smoothie kick now, so for the past few months each morning in goes a cup or more of frozen fruit, the protein, milk, orange. No complaints from this, no bad smells or bad sounds.

Occasionally I've been blending a huge amount of material and held down the "pulse" button except for many seconds at a time. I'm careful with this. I assume that if I did it for too long under load that lovely smell of stressed motor would pop up, but that's really using it beyond its design.

This isn't a very high watt blender and if you need to blend up a ton of material and or a huge amount of frozen fruit maybe you'll want better, but I've really had no complaints at all. If it died today I'd buy another.
