Gives my nails extra strength
Great product giving a chemical free shine and smooth polish finish. My nails have become stronger with no flaking after only 2 applications. Highly recommend for nail recovery if you like to have gels every now and again.

Great for nails
I hesitated spending this much on a buffer as there are cheaper options, but I'm so glad I did. It works very well, giving lovely shiny nails. They are in the best condition now since using it. Pricier, but well worth it. It should last ages with the spare buffer pads included.

Effective, but a Bit Tricky
The Onsen Secret Professional Nail Buffer Block does a good job at giving nails a nice natural shine and helping with post-gel or acrylic recovery. It comes with 4 different sides for buffing and 2 extra shine pads, which is convenient for keeping nails looking healthy. That said, I’m not a huge fan of the manual effort required—it takes a bit of time and patience to get a good polish, especially close to the nail bed where it’s hard to reach. The shine is nice but doesn’t last super long, so you might need to buff again every few days. Overall, it’s effective if you don’t mind the manual work and want a salon-quality finish at home.

Brilliant!
I prefer natural nails, however my finger/toenails have been looking drab with age. Using this brightened and made my nails shine like I'd had a manicure in minutes.

Pricey nail buffer that does the job
Does what it says - nice smooth shiny nails. Shine lasts for a few days. Nails are not stronger though, nails just as likely to break since you are making nail thinner. Is is better than cheaper products? Its a good size so perhaps easier to use but seems equally effective as one I have that is like a nail file. Worth the extra money? Probably not

Very impressed!
My nails were disgusting after gel (never again!) - flaky, ridged, dull and splitting. I tried a different buffer and it didn't make much difference but a quick buff with this was amazing. My nails don't just look better - they look lovely - shiny and smooth.

Qualità e efficacia
Bello trovare prodotti di qualità per Prendere cura delle mie mani durante questo periodo buio. Ho subito ordinate anche il cuticle cream e lime!! Che bella coccola 👏

Great shine!
I'd purchased a cheaper variety a few months ago, and was seriously disappointed - it didn't smooth the nail or do much for the shine. I saw this one and took a chance. It was almost 3x the expense, but you get what you pay for. I am so happy I bought these! Before I got these, my nails seemed to go through different stages between clipping. They would grow out strong and all one length for a few weeks, and after trimming they would get weak and break / split. I haven't had that happen since using these buffers, they're so easy to use. My nails are strong and healthy, and the shine is beautiful.

Didn’t work for me at all.!
Wish I could get a refund on this, I spend 59.94$ on this buffer what a waste.! It came in a pack of 3, only one buffer has been used, rest are untouched.! It doesn’t do anything on my nails, Total fail.!

Never wearing nail polish again
My nails are stunning with this thing. So shiny. I’m never wearing nail polish again because bare nails after this buff looks so elegant and pretty. I think it looks better than clear nail polishes too. I’m busy and life without having to deal with chips and repainting them every few days feels incredible. I apply a nail oil after and some aquaphor on my cuticles and it’s perfection
