This is our second Vitamix.  We purchased our first machine approx. 12 yrs. ago and used it almost daily for 10 yrs.  When the machine stopped working we purchased a bullet and then our kids purchase a Ninja for us.  We used the Ninja for several months, then went back to the bullet and ended up purchasing two other bullets within a 2 yr time until we decided to purchase the new Vitamix.  This machine is just what we needed.  We are using it daily for our morning breakfast and at age 61 I feel great.  Vitamix is the only way to go.
