The ceramic edge blades keep the blade cooler longer. Only drawback is if you drop your clippers as you can risk breakage/chipping. Normally, this doesn't happen unless you are me and rather clumsy.
This is my favorite blade and brand, I shave down ranch dogs with dirty matted coats, bathe, then go over dog again with 7F, just enough hair left to prevent sunburn.
Shipment wasn't as fast as I had hoped, maybe about 2 weeks. But the product is great!
I run a Westie Breeding facility and we groom our own dogs. We needed a ceramic head for our clippers FAST and at the best price. Corro was by far the cheapest we found and the blade came fast and with no problems. I'm going back to order more to have on hand and keeping CORRO on my go-to list for clipper supplies. :)
Great service I had received in a matter of 3 days.
