Before I had the soft top, my Blazer fit in the garage. Now with the rails on the top, it scrapes the garage door pretty hard, so I have to put the top down to get it in the garage... But that's nothing against the soft top, it's just me griping about doing any labor.
The material seems great, very thick, durable material. The frame seems very durable and is in great quality.
There is one thing as far as the quality I may be concerned about over time. For the back window, to secure it down, the way they have that set up I'm not too sure about. And I'll get some pics of it in the morning. It's too dark right now, pics wouldn't turn out.
The way the have it is there's a bar that runs through the back window piece and kinda clips onto a "plastic C-clamp type contraption". Anyways, you have to pull down on the back window piece really hard to get it to go into place which puts ALOT of stress on that plastic piece. It may change, since the material needs to settle a little, but I'll get pics of it in the morning. Other than that, I think everything is great on it.
