I purchased this product for my family several years ago, and it has worked fine so far. It has plenty of speeds in order to blend, frappe, liquefy, or otherwise mix your ingredients of interest. It also has an ingenious "pulse" feature that allows the user to turn off the blender and press the "pulse" button for short bursts of blending power. This is especially useful when blending ingredients that might be easily over-blended and/or require a more delicate approach. For the most part, though, I have used it to make protein shakes and fruit smoothies, and it has worked well and is easy to use. Blending Power Although the motor certainly isn't industrial grade, it has worked fine for my purposes without any signs of degradation or wear. However, the motor may be bogged down or jammed by ice or large chunks of ice; but removing the lid and adjusting the contents will usually alleviate that problem. Just remove it from the device first so you don't accidentally press the pulse button and spray yourself with smoothie......not that I did or anything... :-) Versatility At the time I purchased this product it came with a food processor attachment as well as the standard blender. Ease of Cleaning The blender is best cleaned when disassembled, which can be done by unscrewing the bottom. However, some force must be applied when assembling the blender in order to make sure the gasket doesn't leak, which means it is also difficult to remove. Durability The blending attachment is made of thick, heavy glass and seems very durable. Further, I have had this blender for about 10 years with no signs of problems; and the last Oster blender my family had lasted about 40 years.
