Seen an instant difference as soon as I applied it. It dries very fast and clear too although it doesn't look it on the bottle. The nail varnish went on smooth after. Never seen or used a product like it before but I love it

This does a fantastic job at leaving the nail smooth and ready for a colour. It absorbs nicely so doesn't make a coat of colour on top appear to thick and liable to chip. Only downside for me was the cost.

worked well as a base filled in ridges. worked as described

I quite liked this, it was also went lovely on my toenails as a basecoat!! Smoothed out all my humps and ridges on my nails and worked well with the no7 cuticle oil. Would recommend, especially for toe nails!

My nails are a bit ridged and bumpy, not massively, but it can sometimes make my polish look a bit scruffy. But the results i've had with this base have been perfect. My polish has a smooth, even finish every time. Definitely worth the extra money if you're just using a normal, cheap base and not happy with the results.

I absolutely loved this product from the get go. Smoothed the ridges on my nails with one application. I've always been a fan of buffing my nails to get rid of the ridges but from now on I'll be using this. Perfect under my usual nail polish too!

I've used this approx 5 times now and love it. I have lots of ridges and could never hide them using just nail polish, so I used to buff them off, this left me with brittle nails. This ridge filler is really easy to apply and the brush is nice and chubby so it's on in one swoop. It even makes my nails look great with without polish. It sets really fast so no waiting about. Great little product and worth investing in.

Instantly noticed a difference after applying this for the first time. It is really quick drying as well which is a bonus! Smoothed out all of my ridges and is a perfect base coat.

I used this recently with great hope after noticing lots of dents and scratch son my names. This goes on really easily, covers all 'blemishes' and makes the nail look healthy and shiney.

Unfortunately, the oval shape of the bottle cap makes it hard to hold the flat, wide brush at the correct angle. Average ridge-filling coverage. Nowhere near as good as the now discontinued Boots smoothing Ridge Filler.
