I just finished installing a Vigo Winslow. The quality of it was really impressive. As soon as I opened the box, I could see that they did things right. Every component was packaged separately so they would get scratched. Everything was chromed steel - no plastic. The install went well too. They engineered each piece to give you some adjustment for walls that could be out of square or not plumb. The rollers on the door were also adjustable so that you can be sure that it will stay closed and against the stops. 
I have 2 small complaints. The install instruction didn't provide dimensions. Don't just tell me the "small side wall" or "the large side wall": give me the dimensions. My other concern isn't a problem for us but it's a potential concern for others. Our enclosure was a 36" x 48" with a rolling door on the 48" side and the door opening is pretty small.
