Query: Worst product I ever bought

Perhaps I purchased a lemon, but this was the worst product I ever bought. My old Norelco died after many years of dependable service. Tried this remington model. Didn't shave well at all, battery emptied frequently after 2-3 shaves, and trimmer broke as well. Customer service suggested that I send it back to them and wait. I ran back and back and bought a new Norelco within 6 months.
