I got the kit installed 2 days ago, pretty straight forward instal, wear gloves people those pins are sharp.
Since i used a rev 4 B board i had to solder the wires but the instructions are very clear.
I did struggle to get the encrypted roms to work but it was my mistake, the two middle wires needed to be switched but it is noted on the install guide i just didn't read that.
I'm happy with the multi, even though i had to sell a few of my boards to afford it but it was worth it.
