i'm really annoyed at myself for losing this buffer. it's been a saving grace even after going through the wash and being chewed by cat and dog alike. it's just brilliant and if it's not in your nail care arsenal, it really should be!
to be fair i never really liked the emery board side of this buffer, it just seemed redundant to me and never fully filed my nails how i truly liked them, so i wasn't sad when that part got destroyed.
the rest though, is perfect. it's designed in a way you can hold the file and simply rotate it in your hands to get to the next step. sure, it's a lot of work, but it lasts for ages and there's something deeply satisfying about having freshly buffed nails.
i don't recommend over doing your nails, as the friction from the board rubbing makes it feel like you're a NASCAR driver and you're burning rubber. it's not pleasant and is very ouchy. gently is definitely the way to go.
the only negative is that you can instantly tell when this has been used, even once, as the firm but soft rectangle becomes squishier and harder to use. the edges peel up in places and it becomes quite unattractive. but, when i can find this buffer again i'll gladly repurchase it, and it will have pride of place in my nail kit. love it.
I think this nail buffer is good especially for the price. I find it handy that the buffer is four sided so you can simply just flip the buffet around to use the next side. The rectangular shape and size makes it easy to hold and slide over your nails without applying much pressure. I like that the sides are also different colours so you can easily distinguish between each side and not get mixed up.
It depends on how rough your nails are, but i find a light buff for me gets rid of most of the uneven ridges in my nails. I hardly use side one (for filing the shape of your nail), but find that side four wears done much faster.
I have since switched to using ridge filler now that my buffer is worn out. But i would recommend this product to those wanting a cheap but good quality nail buffer.
