Subtraction loop counter student trainer board

I am a teacher and I wanted to creat a circuit for my students to use for learning how to trouble-shoot and assemble circuits. After some online reseach, and a recommenation from my electrical engineer son, I selected PCBWay to manufacture the boards. I found PCBWay's online process and pricing was quick and efficient. I had my boards completed and sent to me within 8 days of my order. Very impressive turn around time along with constant updates on the progress of my order. When I received my boards they were well packed and looked very well made. I am extremely pleased with PCBway's service, price, and product quality. I highly recommend them.
