Rated 5.0 out of 5.0 by Best Corner Tape Around I've used this tape for a while now and nothing compares for price, ease of use and dependable results. It goes on easily, cuts like a charm and because of the way it's designed usually only needs one good coat of compound and a little touch up sanding for a smooth professional corner every time. Try to cut it the accurate length cuz it's not that easy to cut it on the wall. Then coat the corner with a thin layer of compound or "butter" the tape itself after cutting and bending into a 90 degree corner. Stick it in place and carefully, with a 12" wide compound knife, apply a good even layer of compound and keep going over it until it's smooth and perfect. September 29, 2014
Rated 5.0 out of 5.0 by My new go to for inside corners! I'm no pro. I have no problem mudding and taping, except when it comes to inside corners against the ceiling! I decided to take a chance with something new and I will never go back to regular paper tape for corners! This product made my latest job easy and fast. The corner is much more rigid and was really easy to feather in. I did not have to do a third coat of mud and corners look perfect! September 8, 2015
Rated 5.0 out of 5.0 by Great product Tape had enough rigid strength to make a clean inside corner. Sanded well. Looks great. July 21, 2015
Rated 5.0 out of 5.0 by No need for paper tape ever again. Following the instructions, corners between ceiling and walls are seamless. A third, finis coat of joint compound is almost not needed. June 2, 2015
Rated 5.0 out of 5.0 by Inside corner magic I'm old school and have always used paper tape over anything else. This time I decided to try something new and was impressed. It’s strong and has good reinforcement in the corner, doesn’t fuzz up when sanding, and easy to use. Make sure printed side faces out for both inside and outside corners. I was able to get all the inside corners done of a small room in one day. I highly recommend this! April 24, 2013
Rated 5.0 out of 5.0 by 2 inch x 100 foot Perfect 90 Drywall Joint Tape Inside Corner Corners are the toughest part of mud-n-tape, in my opinion. This tape makes for a solid corner. It can be a little irritating as you really need to make sure it is on 'straight'. If it isn't, you end up with 'warbles' on the sides of the tape edge. Once you get the hang of it, this is awesome corner tape. It doesn't fray, like paper tape so you can knife over it a few times to get it in place. It is also tougher than paper tape, you can get the edge of the knife right in the corner. It CAN be cut by the knife, but with a little practice, you can figure out how hard you can push it. It also hasn't pulled out of the corners nor ripped like I have seen paper tape do. It is considerably thicker than paper, so adjustment needs to be made in how much mud you use on that first coat.

Rated 5.0 out of 5.0 by Works as advertised Works very well for inside corners. Easy to install. May 6, 2015
Rated 5.0 out of 5.0 by Nice edges, inches or cm printed on tape I'm just an amateur when it comes to this stuff, but I've found this easy to use. The edges are kind of perforated so that you can get the mud impregnated into the paper. Also, Inches and feet are printed on the tape as well as in cm. so that you can easily cut off a piece a specific length. This stuff does cost quit a bit more but I went back for a second box.
