Query: Not so great...

I've had this product for a little over a year, and already, the bulbs are dying. The lights go on and then dim off within a minute. The previous make-up mirror I purchased lasted 15 years without the bulbs dying. Also, when pressing the on button to the right to turn it on, it often flips back to the left, and the lights turn off. I've had to push a stapler up against the switch to keep it to stay on.
