I bought this for myself after waiting for the right time to buy them and finally went for it. Upon arrival, I could not wait to open it. After seeing the big red box with the name we all know so well "Feynman" I immediately opened the first volume, and lo and behold, the most beautiful sights for anyone interested in physics. The depths of the descriptions Feynman provides are more amazing than anything else there is out there. I would give this set ten stars if I could.
