I was so excited when this came out, the hype was insane! I rushed out and bought three bottles, black, white and gold. Initially I loved it, although only ever used them two or three times each, because it is pretty dramatic! I found the brush wasn't as wide as I needed it to be, so this would result in either too much shatter, or not enough, which kinda ruins the effect.
The bottles I bought really didn't last long at all before going thick and clumpy, in fact I had hardly used them and had to throw them out :-( As it happens, I've now lost interest in the effect it gave, and would rather have a solid colour, so won't be buying anymore.
I remember when everyone did their nails like this! My white is my favorite because it looks good against any other base colour but i find it hard to get the perfect amount on the nail. Apply to much and the shatter doesn't work but apply to little and it just looks silly. I really like how you get quite alot in the OPI bottles and the polish dries reasonably fast so there's no waiting around. I haven't used any of the shatter colours since they stopped being popular because alot of the 'older folk' have made comments (especially on the white) on how it looks like you've just put correction fluid all over your nails. I have the colours white, red and blue.
Tips: Make sure you apply it evenly and not to much.
