1.0 out of 5 starsPowerful, but loud and has a design flaw - BE AWARE OF FOOD PROCESSOR ATTACHMENT BUILT QUALITY
Reviewed in the United States on August 5, 2016
It's a powerful blender, with nice glass jar and sharp/strong blades.
But it is TOO LOUD when in HIGH speed. It is so loud that it hurt my ears, so I never use in this speed. Fortunately, low and medium speeds do the job nicely.
And unfortunately, today, I've discovered a design flaw in its all metal drive system. There is a square post threaded on top of motor shaft. I've used "Green/Frozen Smoothies" to blend some frozen fruits and this setting uses Dual-Direction blending. It started spinning normally and then reserved the direction of rotation so sudden that the square post has been unscrewed to the shaft. I've tried to screw it back, but the shaft moves freely, so that's too difficult do. Then I screwed a little bit, placed the jar and turned it in on, so the square post have been screwed back "naturally". The problem is that it has not screwed totally, so the disc that stays between shaft and square post keeps spinning after turning blender off. I'm worried about using reversed spinning again and even though they replace my unit, I think it's a design flaw.
[UPDATE 2017-10-04] Now the food processor shaft is broken when making some peanut butter. I expected it to last longer. Really dissapointed.
[UPDATE 2019-03-22] BE AWARE OF FOOD PROCESSOR ATTACHMENT BUILT QUALITY
Blender is still working fine, we are pleased with it. I just want to update this review about food processor attachment. I was planning to buy a new one, but there are so many negative reviews in Oster website about it (part number 164205-001-000). So I disassembled food processor shaft/gearbox to check how it is inside. You can see in the photo that gears are made of a low quality plastic. One of the gears are completely shattered. It is pitiful those parts are not metal, as blender drive is.
[UPDATE 2019-03-28] I contacted Oster Service & Support in their website to ask about food processor shaft/gearbox quality and after 6 days, I have no response.
[UPDATE 2020-03-27] I forgot to edit this to tell Oster sent me a new food processor attachment on 2019-04-04. I looks the same as original one though, so I won't rely on that for tough processing. I'll keep one-star rating because I think products should be built to last.
