Query: Sluggish performance, Broke in just over a year

I used these clippers to groom one miniature poodle. After 6 months I noticed a marked decrease in performance, and just after a year the motor wouldn't turn on anymore. I replaced it with the Oster Golden A5 single-speed clippers and immediately noticed a huge difference. It now takes half the time to trim my dog because the Oster clippers cut more quickly and smoothly than the Andis (even when the Andis was new, it never worked as well as the Oster does). Spend the extra money for a much better product.
