Query: You will LOVE this stuff!!!

I am a 55 year old grandma who has struggled with her fingernails all of her life. I did a search on the internet on products that would strengthen my nails and I ended up on Amazon.com. I have tried dozens of products and this one actually works. I've been able to grow my nails so long that I had to file them down---they were getting so long I couldn't type or play the piano. I am telling everyone who notices my nails about this product. Now, if I could just find a weightloss product that worked!!!!
