Bests & Worsts Reviews from Amazon

Purchased for my mother; received item yesterday. I was expecting to be thrilled with product after seeing it received 4.5 stars and over 2400 reviews! I rarely if ever purchase items without researching. This Zyliss can opener is dollar store quality (i.e. didn't work right out of package). It did not connect to can correctly or continuously and I ended up using a knife to finish opening can. It is being returned immediately. If I could give negative stars, I would.
