I measured many times and built a custom sized door with the guys from Lowes. I was not expecting to pay over $600 for their cheaper model, but the other brands they had were actually a bit more, and I couldn't go with a standard out of the box door because my door width was an odd size. I got the CDMP.
I have never installed a shower door before, but I read and re-read the instructions about 10 times before even starting the demo of the old. The instructions were actually pretty good, but they did leave some questions about sizing and cutting and what to do with this part or that, that could have been more clearly written. I guess I could have called them, too, to ask.
The door went in fine eventually, but I would have thought for over $600, that they would have come up with some better solutions for some of the parts. For instance, the bottom tray, that catches water from going out the front, has a lip on it on the outside, which is good, but it's also dead flat, so after a shower, the water just sits there. With all this precision cutting when they manufacture it, you'd think they'd slope it.
Kind of disappointed that the door side catchall at the bottom also has all these grooves on the inside. Since water is ALWAYS there, why not make it flat or smooth or rounded, now, when I go to have to clean that part, there's all these tiny right angle corners that will be more difficult to get crud out of (I guess all shower door catchalls are like this, though, but INNOVATE!).
Also, the clear rubber vertical strip shield (for lack of a better term) that goes along where the door latches doesn't butt up against the door, so water can slip out that way and down, too.
The door is 100% plum, so I think that's just the way these are built (my mother in law said their door doesn't close the same either, like above)
The glass is nice and the brushed nickel looks real good, but I was a bit disappointed in some of the lack of attention to detail in manufacturing or innovation in ease-of-cleanliness.
Also, silicone caulking sucks. Use mineral spirits on your finger first before sealing it up.
