Lens Perhaps? or Laser to put it simply..I tell you this much..
Neo4 is sh**y modchip. Don't get me wrong it was great while I had it but overall problems for people more than good.
It's like buying a Used Car and then the repair cost endup being more than the cost of the Car itself..That's how Neo4 will be eventually..At least that's for most people..
My advice is Magic2..After that no more hassle..If you want..
