There were several problems with the initial design which Herg also pointed out in his feedback and review (he was one of the initial testers). The first major issue was separation of the ball due to the type of two-part resin that was used in the bonding. The second was it being too dim as I tried to address the loss of color from the first prototype. The third was that for the stance of some players the eye was pointing too low. All of these issues were addressed after the first few that went out.
AkumaZeto, I believe you were sent a replacement, although I'm not positive because you appear to be using a different name to post this review than the name you used to purchase it. If you were not sent a replacement let me know and I can either send you the new design or refund your money. I'm offering a full "no questions asked" refund to anyone who isn't completely satisfied with this mod and it sounds like you are not.
I'm confident the separation issue has been fully resolved but if any of the other 20 that have gone out so far experience this in the current design I would very much like to find out about it. In my own stress tests I literally couldn't break it free (I don't recommend doing this test of course!)
The size of the ball was selected to make the Palantir more prominent than the original version - which I felt was too small. Trying to project any kind of image (or a video) through a ball of the original size would not be worthwhile in my opinion.
The brightness has been improved as much as possible while balancing the "blown out" colors of the eye. Feedback so far from others who received the current version is that this brightness balance was right for their tastes.
