Every time I use it, it smells like burning plastic.
David L. Hubbell
It does a great job of making frozen smoothies and leaves no chunks of ice or fruit.

First, let me respond to a few poor reviews that made me a little concerned about purchasing this blender. One reviewer said "The little plastic "plug" in the lid fell through into the blender as I was using it". He may have gotten a defective one, but the one that I got would have no realistic way for the plastic "plug" to fall through the hole in the lid. It is very well made and would have to be forced VERY HARD for it to even have a chance of making it through - regardless of the angle at which you put the plug. Another reviewer said "the one I received had a jar that did not sit comfortably on base." Again, if that happened I hate it for that guy. The jar I got sat on the base quite well. Another reviewer said, "You CANNOT get your goods back out of this thing without making a mess." The blender I got is very easy to pour from.
Now let me tell you how awesome this thing is. I had a Hamilton Beach blender for a few years that did okay. It would make smoothies and shakes, but would take quite a while and would ALWAYS leave chunks of ice that did not get blended. Even if I left it on for a full minute it would not get the job done. When I used this new Oster 6684 for the first time I made a shake the way that I normally do with some fruit, milk, and ice. After about 10 seconds I could not find a single chuck of ice in the entire shake. In two years with my old blender there were always chunks of ice - always. I could not be any happier with the Oster. Hope this is helpful.

I actually own the Oster 6646 but am writing the review here because the 6646 appears to be no longer caried by Amazon and the 6684 is simply the black version of the 6646.

First, the good: This blender does a very good job of blending ingredients, including frozen ones, into drinks of consistent texture. No lumpy pieces of fruit or bits of ice hiding in the drink. It also does a good job of pulling the ingredients down the side of the jar and around the blades so that everything gets blended properly.

Now, the bad: Shortly after my 1-year warranty expired, I turned on my blender one day and it abruptly turned off after about one second. I actually think this was my fault as I didn't have the jar seated quite right and I had some ice cubes at the bottom of the jar right by the blades. At any rate, to make a long story short I was left with the option to either (a) pay to get the blender repaired, which would have cost over half what one costs new; (b) throw the blender away; or (c) try to fix the thing myself. I had a hunch that perhaps I could find a fuse inside that had blown, so I attempted to take apart the blender. I tried A LOT of different screwdrivers, both at home and at work, and I could not get any of them to grip the screws properly to remove them. I took the blender to my local hardware store and, after a lot of patience, was finally able to remove the screws. While I readily found a fuse, the hardware store said they didn't have a matching replacement fuse. A little frustrated but still determined, I went to yet another hardware store; a seemingly knowledgeable clerk there told me that I would probably have a hard time finding the proper fuse because of the filament design, even though the fuse is labeled as a 5 amp 125 volt fuse.

This is my first blender, and I'm sure there are many other good blenders out there. However I would love to explain why I chose this particulare one and why I love it so much.

It's simple to use, easy to take apart for cleaning, although the base is plastic it is very strong and the gear for the blade in the base is metal unlike the higher end more expensive models which use a plastic or nylon gear. And still, the base is not flimsy and something that can easily break. It really is designed very well with a nice weight to stay put on your counter when blending. It won't be tipping over.

Actually, I would prefer the base made how Oster did this with the plastic/nylon instead of metal, keeping the cost way down instead of $90 to $100 just to have an all metal base.

When I got my Oster 12-speed Blender, trying it out I really liked seeing how powerful the motor is. Actually alot more powerful then I expected for what I paid for it.

Also I really love the fact that the jar itself is actual glass and not some plastic. With a nice heavy weight to it.

I can really see this blender lasting a very long time. Excellent design and construction. Powerful motor. Easy cleaning. Big enough to get the job done but not to big to take up alot of counter space. Metal gear to last a long time. Actual thick glass jar. And priced unbelievably low.

my three month old OSTER 6684 blunder, leaks. Every time I use it, it smells like burning plastic. The bottom plastic, screw on base, is not designed properly. When the base motor spins, it burns the plastic ring. After three months, the ring is worn down enough that the blender now leaks. Since it is over 30 days since I purchased from Amazon, I have contacted Oster, for a replacement. But, So far, not a word from them. Just another company, using their Name and, good reputation, to sell cheap merchandise.

No idea why my updates are disappearing, but I have received a new blender today, what a difference a blender, that is not defective makes. I change my rating to 4 stars ****
