Got it 3-weeks ago...
Quality made unit, the top is adjustable, and it keeps out the noise and conversations on the other side of the door. (I know this; my doctor has one outside his conference room.) This thing is built like it should last for years! I gave it 5-stars because it does what it says, and looks like it should keep on doing it. A little expensive, but over any significant span of years, the cost is relatively miniscule.
Rating: 5 stars
