I just picked three up this past weekend (the mint green, coral, and light blue). So far I've tried out the green and blue. The colours are really cute and stand out but I had the same issues. Started chipping almost immediately and had trouble with the brush. The bottles are a cute shape, but the top makes for a rather unwieldy brush. Then again, for the price you can't really be too picky.

And since we're weighing in on brushes, my favourite so far is the Sally Hansen Complete Salon Manicure (followed by OPI). It's wide so it's easy to get good coverage without streaks.
