Better but haven't ever found best
Works the best of the dozens of products I've tried over the years. But chips/peels within a dew days no matter the prep I use on bare nailbed.

Great product, best I have used!
This is the only base coat I will use. My nails are generally soft, so I need the hardener. It makes a big difference, and I highly recommend.

I have been using this for about 2 months, pretty much having my nails painted most days and I cant believe the difference in the strength of my nails. They used to be so brittle bending, breaking and peeling often. So I am very pleased. I have used it for a top coat, which I'd recommend. I've also used it as a base coat, though I wouldn't recommend this as I found it caused the nail polish to chip off and peel away, and I was wearing OPI nail varnish, so it was this. But when I used it onto of my OPI is made all the difference. Hope this helps.

I have the worst nails, I bit them all my life but since using this my nails have been getting harder ever day and strengthening. I will definitely buy this product again.

Works great as a base coat. No comments about the hardening etc because my nails are healthy and I can't tell. But the brush! WOW. It's thick enough to pick up the perfect amount of polish. The shape is perfect so that a single swipe can cover most of the nail. When you use it, you realise what you've been missing out on with other nail polishes. One of those quality of life improvements that hits just right. MVP brush for reals.

During COVID I can’t get my nails done. They were a mess. Until I bought KUR. Excellent product.
