Bests & Worsts Reviews from Amazon

I purposely waited a bit to write this review to see if this item would hold up, and unfortunately it did not. As for the power and ability to make a great smoothie, it is fantastic. However, it is a cheap piece of plastic except for the motor and wears out very easily. The blade assembly that you insert into the motor must be situated exactly right. If not, it could easily strip the unit. This is what happened to me, basically rendering the unit useless. I called Ninja since this is well within warranty but was told the warranty was for the motor only and a blade replacement was not available. However, they would be willing to replace the whole unit for the cost of the blade assembly which was $39.99 plus $6.99 shipping and sales tax. So basically, I would be paying another $49.99 for a replacement unit that I already paid $69.99 for back in January, and probably would not last anyway? It makes no sense to me and I won't do it.
