We bought this to replace our old Ninja System, which we had for over 7 years. This new system did not disappoint. It's built off the same quality as the older systems, but with much improvement.  We actually originally tried replacing our old system with a Vitamin and it was AWFUL - it didn't even work out of the box, and when we did get a unit that worked the performance was poor. Not to mention it cost 4x the amount of the new Ninja system. Couldn't be happier with our new Ninja system, and definitely won't ever stray and try something else.
