Review on Primary Concepts Hourglass Adaptor Classroom by Richard Cheng

Nice concept and it works as expected. The volume of the timer and noise alarm can be regulated and is very loud. Large lights are easily visible even in a fully lit room. However, the quality of the product does not match the price of $100 - The sticker describing the time and noise level is bubbling - The product arrived with many scratches - There are two lines on the white plastic cover (which covers the LEDs) - The screw to the battery compartment is not screwed in. Overall a good idea but poor quality! I sent this item back the next day.
