I bought this product about 18 months ago. It did an excellent job just as described by the manufacture. I was very satisfied and used it each morning (I mean every morning). I told all my friends that this is the best product ever made in China.
Well, 6 months later, the soymilk button (the right button) stopped working. So I used the middle button instead. This woked fine and I was still very satisfied.
Last week, the middle button quitted on me. So did the 3rd button.
If the product can last, say, over 3 years, I'd be satisfied.
If the product can last, say, over 5 years, I'd be satisfied, very.
However, if the product lasted only 1.5 yrs, I'm not satisfied. That's why I gave 3*s.
In conclusion, This product has a very good initial quality.
But it lacks reliability. It cannot maintain the good quality over time.
I hope that the manufacture put more effort in improving product reliability.
