Are you sure we are talking about the same products? MP's are made of one solid piece of resin - no seams - and I've dropped mines more times than I can count in the shower and never had it break. And the rake has a heck of a lot more than 10 tines. 
They are completely seamless. You do want to be careful if you have thick tangled hair (especially with the thinner combs) - I broke a rattail on my daughter's 4z hair before it was relaxed.
I've never been interested in the brush, as I don't have a need for a brush for my hair.
I am actually thinking about getting the brush. I brushed my hair with the Goody jojoba brush the other day and it looked sooo fluffy!! So it made me consider looking in to the MP brushes. Also, ladies if your comb breaks, contact MP and I'm certain they will replace it (as long as you purchased it from a dealer). Remember, there are fakes out there so be careful where you purchase them from.
Interesting. I have a seamless comb but it's just generic. Is there any reason why this one is so much better? Does it hold up better than other combs...detangle better?I think that using seamless products on your hair reduces the mechanical damage done to your hair, and since mechanical damage is one of the causes of split ends and breakage, I think that consistently using seam free products will, over time, improve the overall health of your hair. Those tiny seams on combs can act like fine razors, scraping and scratching microscopic bits of cuticle off of my hair - and since I want my hair to manage to be 11 years old and still looking good, I really can't afford any cuticle loss!
Can I say, for certain, that since I've used this stuff I'm seeing less breakage and splits? Yeah, I can, but I've also changed a lot of other stuff in the period I've been using them, so they can't get all the credit. Do I think I would be seeing more breakage/splits than I'm seeing now if I wasn't using them? Yeah, I do, which is why I shelled out the loot, but I've got no proof, ya know?
