The 1200 series should seriously come with earmuffs.between the sound of the blade and the motor,it is so loud.my 900 series finally died after 7 years of great service and I wish I had bought another one instead of the 1200.does the same job and so much quieter.

We had one of the original NutriBullet 600's for years using it more than once daily. Eventually it starting making some noises so we decided with a bit of sadness to retire it.

This NutriBullet has a different blade set up with the blades higher than the original. With this blade I almost always have unblended banana in the bottom of my smoothie. The old one came with a milling blade as well, which this one does not. Its not a deal breaker annoying as I did not get this with the old one.

Probably the most annoying thing is that it blends...

I purchased this one as a replacement for my old 1200. The blades are different and unfortunately did not blend up the chopped frozen fruit. The previous one had no problem, this blades have to much of a gap between them. Although I do not use it, it states on the box it blends hot liquid but in the instructions it says no hot liquid was a bit confused about that one as well.
