Review on Layers Clear Stackable Raspberry Heatsink by Christopher Wells

Arrived quickly. Easy assembly even for the inexperienced. Looks nice. You get 4 clear acrylic plates to mount the Pi 4 on and a top plate for the demo which I didn't use because I have an ice cooler on the Pi. The kit includes all the necessary racks and heatsinks for 4-Pi boards. I would recommend not using the included silver screws to attach the Pi to the board, but instead using a slightly longer black nylon stand which looks better and allows more airflow under each Pi. The kit includes top nuts which provide maximum security in my setup. Very happy with price and set. If you have more than one Pi I would recommend it.
