I've been under a lot of stress these past 30 days, including three very bad breaks to my nails that couldn't have been avoided. However, as a whole, my nails were definitely stronger than normal. I didn't have any problems with chipping or splitting but I can't say that they grew any faster - which wasn't a claim of the company anyway. Overall, I am happy with this product as far as a strengthener, but I don't feel that I would replace my base coat completely just yet.
