Very good but not perfect
Pros:  light shines through the clear attachments so you can put the light directly where you need it in the back of your mouth.  Little scoop on end of tip lets you scrape out what you need to.<br /><br />Cons:  only one attachment is long enough for me.  The rest are too short to be very effective.  If you put the lighted tip behind some tissue in your mouth, you can't see what you are doing anymore because the light comes out the tip of the attachment.<br /><br />Overall, a useful tool.  Has room for improvement (perhaps longer attachments and a secondary light on the handle that shines directly on the spot you want to illuminate when the light that is shining through the attachment is obscured).
Rating: 4 stars
