I am very impressed at how well this thing works. I installed Rebug 3.55.2 True Blue Edition cfw. I simply installed it over 3.55cfw. I then installed the update2.3.pkg and updated the dongle.
I already applied all the TB patches to the games. This thing works great. Just played some Rayman Origins and Portal 2. The dongle itself feels really well built. It is a aluminum casing which feels very solid.
Just wanted to share that with you guys.
