Product review (2 stars): Dissapointing and un-usable without signficant modification.
Although the price was right, the actual product was quite disappointing. I mounted the bracket to the ceiling, cut the holes, only to find out that screw holes would not align, I would have had to drill holes all the way around to get the cover in place.
Additional Issues:
- The expandable vent tubing that it comes with is plastic.
- Pressing the buttons results in excessively loud beep
- Blue LED light from screen and buttons shines directly into your eyes, with no way to dim or shut off display.

On a positive note, I had no problems returning the item for a full and complete refund. Based on the number of issues, it did not appear that this unit was an anomaly.
