I bought this about a year and a half ago (Nov '19) and worked great for the first year until the blades suddenly just detached.
It was a pain to put it back together but made me realize how much liquid had leaked inside the shaft and was turning bad because it couldn't be cleaned properly.
I tried cleaning it and sterilizing it, and that warped the plastic inside so it rendered the tool unusable as I'm not able to buy a replacement part just for the shaft.
So, the only good thing about this product, is it's power and electronics, but in the end, it doesn't really serves well its purpose.
