This stuff is awful! I've seen many great reviews about this nail polish and seen bloggers post pictures of their beautifully manicured nails using this product.
I bought four different shades as I thought maybe I had a bad batch but nope the formula was bad for all four shades.
The nail varnish has a thin, milky texture which is prone to bubbling. I found it hard to make the colour opaque, even with three coats my nails were very streaky. The brush is OK but the formula is difficult to apply as it runs all over the place and settles into the cuticles.
Even though the formula is thin I still had difficulty getting this product to dry. As the polish never really dried completely I ended up smudging the polish and taking it off as it looked awful on my nails.
This is a very cheap nail varnish so it is worth purchasing to see if you like it or not. I am prone to have dreadful result with Sally Hansen products as this brand as a whole does not work well with my nail type (thin, dry and brittle).
On the plus side this brand does have a large color selection and there are some really beautiful shades.
To be honest I only bought this because you had to spend a certain amount at Farmers to get this GWP and I needed an extra few dollars. I am pleasantly surprised though, it's great for everyday wear when I can't be bothered having a full manicure on my hands.
The formula is very thin, and as a result dries super fast. I usually just do one coat of it on top of my bare nails for a slightly shinier 'natural' nail; or if I want it to look glossy I'd use two coats. I find that on its own as a clear polish it lasts about a week before it's so chipped that it's noticeable. However on top of a color polish it's not so long lasting, so I don't often use this as a top coat.
The brush is quite long and thin, which is fine since I only need to do a thin coat but I would have liked a thicker, wider brush. No idea why it's called 'hard as nails', as you'd probably need 10 coats for it to be equivalent to one coat of gel polish.
It's not bad, considering how cheap it is and that I can just do a quick coat and run out the door in 10 minutes.
