I used to use a M & S crystal file until I dropped and broke it. I replaced it with a Leighton Denny file and didn't find any difference between the two.
I love my crystal file and definitely feel that it helps my nails, although I always find at this time of year that they peel more than normal - probably because they're covered up in gloves all the time and don't get any sunlight. Well, that's my theory anyway!
