I got this nutribullet blender just over a year ago, and it went into the trash today.  It worked great for about 6 months.  I use it every morning to make a smoothie, either one in the individual cup, or two in the big container.  After 6 months it started getting louder and louder, then grease started coming out and was all over the motor,  today little shards of metal came out with the grease and it started making really funny sounds.  I shut it down and emailed nutribullet, I haven’t heard back. I’ve been using the smaller nutribullet for years, which works great, don’t be bothered with this blender.
