I was really skeptical about its power to crush frozen  fruits and ice. The main competitors offer the same feature for much higher price. Therefore I was doubting its  quality. However I’ve decided to give it a try as I was not ready to splash money on more expensive device. I’m really happy with my purchase and that I saved money. Ninja does the job, also it’s really easy to wash.
I gave 4 stars because it’s a bit more noisy than I’ve expected.
