Works well; durable; good value [SEP] I started using a tongue scraper a few years ago after receiving a plastic one in a kit from my dentist.  These stainless steel scrapers are much more durable and they work well, although a little narrow for a full-sized adult mouth.  However, I was able to carefully bend one to a slightly bigger radius so it's more comfortable for me to use.  And at $11 for a 4-pack, I could share with my spouse and child and still have a spare.  I don't know if these are really "surgical grade" stainless, but they're non-magnetic so not made of cheap steel.  I'd buy more if I ever had the need, but I doubt that the first set will ever wear out.
