Rated 5.0 out of 5.0 by sngz4hm Worth every cent
I installed drywall in an unfinished attic in a 74 year old house with uneven rafters, floors, and wall studs. Even though I leveled the new ceiling joists and plumbed the wall studs I ended up with joints that had large gaps and snaked across the room. Several DIY websites recommended the Ultraflex not only as a corner bead replacement but for tray ceilings with off-angles joints like mine. It was much easier to install and finish than traditional drywall tape or metal corner bead and did a great job covering the large gaps and straightening the joint lines (see before and after pictures).

Rated 5.0 out of 5.0 by mdstaz The best for vaulted ceilings
After my sheetrock installers tried 3 times to get a 30' long 45 degree joint straight, we went back one more time with UltraFlex 450 and got the straight joint we were seeking.

Rated 5.0 out of 5.0 by Renovatrix Great product
This will make even novice drywallers look like pros. And 'though it costs more, it makes up for it by saving you from headaches. I used it to
finish an attic remodel where-- trust me-- nothing was straight, flush, level or plumb. Plus, being an attic, I had tons of odd angles to deal with. I ended up with crisp, straight lines and good-looking angles. The corners really resist denting too, unlike metal corner beads. I hate drywalling but loved working with this stuff because it made it just that much easier and the end project looks great.

This product is one that will reward those who take the leap and try it. After so many bad examples of mediocre products, installation methods and failed adhesion, this one was nirvana. Professional results with just a little bit of thinking and care.
Why it is not stocked is beyond me, I need another box TODAY and have to pick it up from another supplier. This should be in the stores!

Rated 5.0 out of 5.0 by Honeydeux It makes my corners perfect and so easy. Worth every cent. Saved me time, mud, and I'll never dread corners again.
I am a major DIYer & there is almost nothing I don't do except plumbing. I read about this product in a home improvement magazine-maybe The Family Handyman. When I had to tape and float a complex stairwell, so I found the article and had to order the proct from Home Depot on line. In three days I had the product and used it with amazing ease the next day. I had to do 45 & 90 degree angles - all with ease! I'll never use paper tape or metal edge corners for drywall again :-)

Rated 2.0 out of 5.0 by JoeHandyman Only useful for off-angle corners
1) I bought this product to finish off-angle corners, it worked great for those, inside and outside. Since I had extra, I figured I would use it on all 90* inside and outside corners.
2) On the outside corners it went on OK, but started popping out during subsequent mudding coats. I ended up needing to put dryall screws in it to hold it tight. I drilled holes in the plastic first to keep it from twisting as the screws went in. I needed to do this after painting too, as it continued to pop. In hindsight, I would have rather used metal/paper, these are a little harder to go on, but I've never had one pop after install.
3) on the inside 90* corners it worked better, but it is significantly thicker than other tapes, so it required a lot more mudding finish work to get to look level and smooth. Again, I had better luck with tape that this stuff.
Bottom line, if you have off angle joints, this works great. For 90* stick with other methods.

Rated 5.0 out of 5.0 by SmalltimeBuilder Perfect for odd angles and corners that like to crack, but not a catch-all replacement
This is a great product for the 135 degree angles in a bay window (or whatever angles they end up being). As advertised, it's truly strong, and I used it to redress corners that had stress cracks in them (thanks to the entirely unforgiving nature of sheetrock mud, and finding out too late that mesh tape is like a crack waiting to happen). This high-tech tape is so stout that I doubt the cracks can ever show back up (and perhaps a layer of paper tape would have been sufficient, but I wanted to be certain).
All that said, I can't imagine anyone being able to justify the expense and more tricky installation process to use this product on typical corners. The fragile paper edges get beat up during storage/shipping, since they cannot roll together tightly enough to protect themselves. You must make sure to unfold/flatten the edges before install, or you risk damage (crimping/tearing the thin yet crucial paper edges).
This is not a simple, flat product like the tape you are used to--it likes to hold its previous shape (and since it comes in a roll, this means you have to work it a bit to make it behave). One gentleman on here complained of it popping out of his mud, and this is probably because the product is so stiff. You have to dry-fit this tape, over-bending it beforehand until it likes the shape you want it to stay in; then, installation goes smoothly and the mud holds it flush.
These are realities that no amount of specialized tools are going to fix. But if you need that strength and flexibility for a corner, this is the product to use.

Used on drywall corners, both inside and outside corners. This was our first time using it, but think we should have pressed out the mud more to make height more consistant along the drywall. Will use again if we ever have to drywall.
