Bests & Worsts Reviews from Amazon

This review is for a metal gear box case version. The metal case does not improve any of the product quality. I broke 2 of this, each were withing 20 usages with instructed speed 2. I am an aerospace engineer, and I attended a professional bakery course and in hope to star my bakery shop. I bought this product to test my recipe before I can go full scale production, unfortunately this product has very short life span. First, it heats up quickly. The heating may due to too much gear box friction, the load of mixing the dough and the lack of air ventilation. The machine shuts itself down frequently. After about 15 uses, the gear stripped and failed. I chat the customer service online, and they told me the gear box is not included in the warranty, but they are willing to send me a new one just for this time. So, I got a new only in few days, and send the broken unit back to them. However, the new machine does not have a longer life span. I failed again for the same reason. Please view the photo I posted with the product page. It's so obvious that the gear box is full of metal chips. The teeth are too fine to handle the loading, or the gear is made of cheap materials. Hope this will help when you are selecting a mixer.
