What is it?

Ninja Master Prep Blender

You may know this model best from late night soirees with your couch and the QVC channel, but the Ninja Master Prep Professional blender managed to top the scorecard alongside a Vitamix 5200 in the latest round of Consumer Reports blender testing:

Overall scores aside, these are two very different devices (and not just in their price tags). The Ninja features a unique top-mounted motor that you have to press down on to operate. …We used the largest container for our various blending tests, in which the Ninja made a superb smoothie and frozen cocktail, pureed soup to smooth consistency, and crushed ice into fluffy snow.

But wait, there’s more!

ninja master prep bladesWhat we like:

This Ninja blender has almost universally positive reviews, and by all accounts does its job fairly well.  Most consumers seem pleased with it, at least initially, stating that it makes smoothies easily and performs as a food processor to their satisfaction.

The chopper system with its quad blades works fairly well, as long as you’re careful to follow instructions and use the pulse function.  It even does a good job cutting cold cheese up – one of the more difficult ingredients for most chopper systems since it has a tendency to gum up the base.  The quad chopping blades work well to achieve thorough and consistent results when cutting vegetables like garlic and onions.

What we don’t:

Some people report having difficulty fitting the motor on top of the processor bowl and pitcher correctly so that the blade shaft engages the motor.  This is particularly important since if you’re adding ingredients mid-processing, you will be prying off the top and realigning it fairly often.

Since the blade shaft fits directly in the motor, if the contents get spilled or splash over the top of the shaft, stuff is going to get jammed into the motor top piece.  You obviously cannot put the motor in the dishwasher which means the top piece is going to get dirty with no good way of cleaning it out unless you are careful with it.

The detail that concerns us the most however, is the fact that many of the Ninja blender parts are made of plastic, including the part where the drive shaft meets the motor.  This means that it is very, very easy for it to get stripped.  This will leave the blender rather unusable, and indeed almost every one of the sparse but consistent negative reviews complain about this exact issue.

Where’s it made?

Should you buy it?

At the end of the day, the overwhelmingly positive feedback on this item give it some credibility as a solid purchase – we just really wish that the company had spent a few more cents and made the blender parts out of metal instead of easily breakable plastic.  Even the disappointed customers mostly found that it worked well for them initially; it was only after some time that the blender would fail.  Even keeping that in mind though, the low price and great reviews across the board make this an attractive blender to give a shot.

Ninja actually released a new and updated product, the Ninja Master Prep Professional blender. However instead of replacing the critical plastic parts, the updated unit merely seems to have added an extra prep bowl and increased the wattage of the motor slightly.
