How did I like it? I found that the claim of a 90 second dry time really was quite true, or at least a 2 minute dry time was very easily obtained. My nails were dry to the touch in about 2 minutes, and completely dry in 5. Very lovely. The shtuff itself did not get goopy once I got down past the halfway mark, but stayed nice and thin. However, the thin part is something I wanted to talk about. Mega Shine really was not shiny and thick enough for me - I quite like how Seche lays such a thick layer over the polish, since it makes it impervious to chips and beautifully mirror-like. Mega Shine has a thin formula, and does not form this lovely thick layer.
In conclusion, I liked Mega Shine, but I did not stop there. I am pushing on with my search to find a new topcoat! :)
