I've tried other similar models from Revlon and other drugstore brands. Most buffers get the job done, so I assumed this would be just another buffer. No big difference. File, smooth, buff to shine. However, this particular buffer seems to get the job done exceptionally well. The smooth surfaces smooths really well and the buffing surface makes my nails nearly twice as shiny as any other buffing block I've ever tried. The shine lasts for days and it looks like I'm wearing clear polish. It takes only a few minutes to buff all my nails and toenails. The only downside is that this buffer only seems to last about 2 uses. I wish Body Shop would substitute the emery board type surface (which I never use since I have better emery boards) with a second buffing surface. That way this block would last twice as long. I don't love having to toss this into the landfill after just a few uses, so I'm subtracting a star since this product has short longevity.
