There are numerous reports and videos about the pickups. I bought them as a replacement for my Kramer Pacer Classic and I'm completely satisfied. Absolutely clear, tidy sound. Whether it's a fat humbucker or a fine single cool sound thanks to coil split... It's all there and sounds excellent. Everything you need to install it is included. You do have to solder it yourself, but that's completely understandable considering the many installation options. On my guitar, the electronics compartment is big enough to accommodate the additional 9V block. This meant that everything could be installed neatly. Clearly recommended!
