No complaints
Fantastic product, noticeable difference during and after use. Very strong coating when using it and strengthens the nail underneath so you develop naturally stronger nails the more you use it. Easy to use and cant really fault it. One of the best ones of its kind that I've tried for an affordable price

Pricey
I do think this product is a bit pricey for what it does. I've been using it as per instructions, and can't say I've seen much change to my nails. I do think they are a little stronger but still brittle. However, everyone's nails are different and this may work better for others.

Excellent for soft nail protection and growth.
I have soft bendy nails that do not grow well. This treatment makes them stronger and helps to grow. When I don’t use it my nails don’t grown and they remain soft/easy to peel

My Go-To Nail Strengthener
I have purchased this nail strengthener several times, and it has become one of my favorite nail care products. It dries quickly, is easy to apply, and leaves a smooth, clear finish that works well on its own or as a base coat. With consistent use, I've noticed that my nails feel stronger and are less likely to peel or break. It also helps them grow longer while maintaining a healthier appearance. Overall, this is a product I continue to repurchase because it delivers reliable results. If you're looking for an effective nail strengthener for weak or brittle nails, I highly recommend giving this one a try.
