so what are the advantages of the raptor board in a box mod compared to a OKL t20 board? they seem to cost almost twice as much from what ive seen so what makes them better? they both seem to have a lot of the same important specs so is it something like lifespan or extra features? is the raptor US made and the OKL is from overseas or is the raptor just harder to work with or something? please chime in with any insight because im thinking about purchasing one of them or a sigelei 150w.
