Perfect Joints!
The MF-100 Straight-Flex Mid-Flex 3 product worked just as described. It performed perfectly for my >90 degree joints. My project was a remodel of a textured ceiling. The joints were not originally finished with precision as the texture covered all the imperfections. The Straight-Flex gave me perfect joints. Two tips: 1) After the Straight-Flex is placed in the initial joint compound bed make sure to pull most of the compound out with your sheetrock knife. All you want is a thin layer underneath the product. Then let it dry overnight. 2) Make sure not to get the joint compound in the corner as you place the finish coat on the Straight-Flex. There is a blue line down the center where it bends and forms the corner. Make sure you can still see the blue line. This will give you a perfect corner joint. Definitely recommend this product.

Love this!
I had less than and greater than 45degree angles to put corner bead on and this was great. Good on 90 degree corners as well. A very good timesaving product. There are good You Tube videos how to use it by Vancouver Carpenter

I've used 'No Coat" before, this one is cheaper and seems to be just as good, maybe even easier to use

Great!
This stuff made drywall finishing a ton easier on off corners as well as inside 90's. I would definitely buy again! Worth every penny!!

Strong but flexible. Cleanest corners I’ve ever had!
I love this product! It was so easy getting clean lines on my corners, odd angled walls,, and even patched a small hole with it. Too bad I didn’t discover this years ago!

I love the fact that the specifications for this tape list that it is 10" long and 1 horsepower.
If you check the image of the box it tells you that there are 100 feet of tape in the box, but... Could y'all please add that to the description? I'm pretty sure this tape is 0 horsepower, since it is (hopefully) not internal-combustion tape...
