Genmega, Hantle, Hyosung High Bright Topper 19x15. The original mounting bracket for this topper was designed for flat based Hyosung ATM's or a few Genmega flat based models such as the C4000 or G6000. I fabricated an angled bracket making these toppers compatible with all Genmega and Hyosung machines regardless of whether they are flat or angled. These toppers are without a doubt the brightest toppers ever produced and sold by Hyosung or Genmega. They're solid and were certainly built to last forever. I cannot speak for Hyosung, but Genmega doesn't manufacture these anymore. Nowadays they produce cheap plastic light up boards that are more cost efficient but by far less superior in every way.
