Works Great!
This product is awesome!! It works, and gives your nails an unbelievable hard-coat-super-shine!! Not sure the science of how this works... but it is witchcraft!!! I love it!! Works fantastic on natural nails, and acrylic nails. The shine NEVER fades or leaves, and doesn't really scratch. You don't have to re-do the filing process ever! I get my acrylic nails done professionally by my friend. I bring this bad jackson, instead of a doing a gel top coat. This is WAY better than a gel top coat. I gave an overall 5-stars, but I do have a couple of gripes... 1. It seems pretty flimsy... so I am really unsure how long the file will last. 2. It is $$PRICEY$$ for this tiny, flimsy thing!!! I mean way to expensive!!! If the file lasts and lasts... then it would be worth the price. I will just have to see how long it lasts!! UPDATE- JUNE 30 2020: I will stick with my original statement that it works, and makes your nails WAY shiny!!!! However, as you can see from my pics the shining side is completely flaking and falling apart. Keep in mind, it's flaking after literally 3 uses. Wow!!! I love how good it works, but would NOT purchase again!!! It's literally worthless now, because the shining side of the block is completely peeled off. It's way to expensive as well. No, just no!! UPDATE- JULY 2 2020: I contacted the company personally from their website (not through Amazon, since my return window had closed), and told them about how the buffing block was falling apart. I also sent in the pictures. They immediately offered me two options. 1. Get a full refund (even though the return window on Amazon had closed), and keep the original buffing block I paid for OR 2. Have a new buffing block sent to me free of charge, and still keep the original buffing block I paid for. I chose another buffing block. The customer service was awesome!! I bought this on 5/4/20 and could return it back through Amazon up until 6/3/20. Even being past the return date, they STILL helped me!! I appreciate that, and definitely will change my mind and order from them again.

Amazing results . I have tried everything from supplements to nail strengthening polish. My nails are thin and always chip and peel. This product has actually strengthen my nails and gives them a polish look. I never expected such a great result so quickly

Really like this
I honestly like this buffer. Made my toenails look like they were polished. Same with my nails but had to really use strength while buffing. Only four stars because they don’t last as long as they used to.

Great product
UPDATE: I only got one use out of white sides for shine. I had to replace with the included replacements. I will probably try a different product that lasts longer next time. Item works well. Nails were damaged from gels and acrylics, and I have ridges in my nails. Initially, after using the product, I couldn’t figure out why my nails were not shiny and glossier like the advertisement pictures. Then I figured out you have to use the smooth white part of the file last. That’s what gives it the shine. I don’t know how long the shine will last yet but I’m happy with the product so far. The first picture is after I have used the clarify side and the boost side. The second picture is after I use the plain white side for shine.

Simple Yet Effective!
Gave this to my daughter as a gift. She told me later after using it that she loved it and felt her nails were healthier after one use. She loved how they shined and mentioned not using nail polish anymore. She also liked that it was so simple and compact to use compared with many of other products she had bought and used in the past. She is very picky about things so i felt i had chosen well. Elizabeth

Decent block, nothing amazing; don’t use too often or nails will be thinned and damaged
First, note that any buffing block like this, no matter the brand, is damaging to the nails. You’re essentially filing off the nail’s top layer of keratin with a fine sandpaper, then buffing it to a shine. So it certainly shouldn’t be done often, especially if you have naturally thin or brittle nails to begin with. So use sparingly and/or only on very thick and healthy natural nails! That being said, I bought this because after keeping my nails painted with regular polish practically 24/7 for over a year, they started peeling in sheets from the tips, no matter what products, brands, and techniques I tried. I knew I wanted to take a step back from polish and allow the peeling tips to grow out, but still find a way to keep my natural nails looking shiny and smooth without polish. So, I decided to try this buffer once to give my natural nails a “fresh start.” It’s expensive for a single buffing block and I didn’t find that it really performed any better than a cheaper block from a beauty supply store. It gave me a nice smooth feeling and a shine, but nothing super glossy or glass-like. I did go easier with the sanding steps to protect my already-thin nails. The more you sand off, the more shine you’ll likely get (but the more damaging). The initial shine only lasted about 4 days for me before I felt like it was starting to dull and needed to be polished again with the smooth side of the block. Bit disappointing considering they advertise 10 days of shine. I did get 10 days out of using it for a pedicure, though, since socks act like protection. My photos show a before and after on both hands. I do like that they sell replacement pads, but so far the block has held up fine for me after doing a manicure and pedicure. Obviously don’t dig the tips of your nails into the buffer and it won’t become scratched up like some reviews show. You should just be gently gliding it over the surface of the nail, not digging the tips of your nails into it. Since I only plan to use this infrequently, I justified paying $13. But if you’re someone whose thick nails can stand up to more frequent buffing without taking on too much damage, I’d say go with a cheaper block from a beauty supply store and get the same result. Also, don’t fall for the “Japanese” marketing - as far as I can tell, Onsen is an American brand owned by an American man who visited Japan once and now names his products things like “onsen” and “pagoda" for the foreign appeal.

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

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.
