I had a very good experience with customer service, I called the 855 number and chose to have a return call. The operator called back within 20 minutes and took care of my issue.
I am having an issue with the blade assembly. If I use frozen fruit, the gasket is coming loose from the blade assembly, which is not supposed to happen. I followed the recommendation from customer service to let the frozen fruit sit at room temperature for 3 minutes, I let it sit for 15 minutes, the gasket still came loose and came out of the blade assembly.
I love my Nutribullet, I hope that this issue can be resolved.
