I spent 80 bucks on two lengths, to do three doorways and threshold for a laundry area.
The biggest problem is you basically can’t test fit anything, because as soon as it starts to slot into the track, the stupid cardboard tabs will break off if you try to pull it back out.
The laundry area is OK-ish. The problem there is that I needed the transition down, but not as much as the piece they give you has. Trying to trim it clean and straight was a nightmare. It looks OK from 5 feet, but if you actually look at it there are all kinds of gaps and unevenness.
Another bedroom was just a simple T molding, but it’s sitting loosely and again has gaps with the floor. I suspect the tabs cracked
