Low profile, but not as low as a Tomb. Not a flat top either.
For me, probably throwing it max 60m, it's straight with a tad of understability. I was hoping for something more understable but it will probably make a good tunnel disc.
The initial glow is bright but it quickly dims to being just enough to pick it out from amongst the grass - so better than many but definitely not the best - useable for a glow round but not for more than one throw per charge up.
