This microwave was purchased new online. Packaged well and luckily, no damage in transport. We have yet to use all of the available functions, have had it for only a few months. However, we're enjoying it overall. The only suggestion I would have for Samsung in regards to this product would be to include a better owner's manual that is written concisely and maybe a little better presentation with it. Example, the auto defrost feature section does not note that maximum weight limit is 3.5 lbs. Would have been nice to find that detailed in the manual instead of having to go online and find out if my microwave was broken because it would not accept input of higher value. I was preparing to ask for a service call because I thought it was an equipment failure. Other than that, I enjoy Samsung and think their products are well-made overall.
