Excellent product
Great product and service. My block cracked at one of the ribs. Made a warranty claim and sent in a picture of the damage. They sent a new block no questions asked. They stand by their product.

12 inch ultra flex
Like the way you can grab it. And it does keep a smooth surface, but to be an ultra flex it does not flex very well to my opinion, but it is still a good tool. Their service is outstanding. I had an issue, and they took care of very fast. Thanks.
