For the price tag most reviewers were pleased with the Oster 6647 blender. This 10 Speed Blender offers the high power required to make milkshakes, smoothies or salsa and crushes ice with ease due to its powerful motor. The ten speeds also allow for maximum control over the consistency of the final product.

Oster 6647 Blender

The 6647 Oster Blender features a strong 450 watt motor that is designed to provide lasting durability. The blender provides ten different speed settings so it can be used for a wide range of jobs in the kitchen, from stirring to pureeing or crushing ice.

Other Oster 6647 Blender Features

This blender has a specially designed stainless steel blade to crush ice so that the result is perfect every time. It also features a pulse setting so you can chop food to the exact consistency you desire.

The jar is made of glass and is dishwasher safe; it also features a nice design, making it ideal for serving. The controls are push button, so they are extremely easy to clean and the unit also has cord storage which can be a lifesaver for saving storage space.

It seems that the most prominent advantage of this blender is the very low price for a blender. Additionally, the power of the motor makes it an excellent blender that can handle virtually any job. The all-metal drive also increases the durability of the unit.

It also seems that the Oster brand is associated with reliability as many people have owned a unit for five to ten years and do not want to switch to another brand. This is owed to its reliability, its performance as well as its price, which is much lower than many other brands which often exhibit major problems.


There were several complaints regarding the 6647 Oster Blender leaking but it seems this was mostly due to the fact that the seal was not positioned correctly. Additionally, it seems that some of the parts are rather fragile, especially the lid. Some people experienced problems with the design of the lid as part of it has fallen into the blender while it was working and ended up chopped to pieces inside the smoothie the customer was making.

Additionally, it appears that the different speeds on the Oster 10 Speed Blender are not quite as effective as they seem to be, with little difference between them. Not all reviewers were lucky when it came to crushing ice and some had problems with blending softer ingredients as well as it seems the unit doesn’t offer adequate flow to move the ingredients around so that the blade can chop them all.

There have also been reports on the blender dying after a few uses and in one case it was on the first use. Some parts, including the lid, seem to warp in the dishwasher. However, only the glass jar of the Oster 10 Speed Blender is designed to be cleaned in the dishwasher which may have something to do with the problem.


As with any product there are those who love the 6647 oster blender and those you aren’t overly impressed. However, for the price tag most reviewers were pleased with the Oster 10 Speed Blender’s performance.

It seems that the main problem with the unit is with brittle plastic parts that don’t seem to be able to hold up to much stress. The primary complaint about it may not necessarily be attributed to a design flaw since the product does not state that they are meant to be cleaned in the dishwasher.
