Thanks for posting. I (the person who started the tread) have already bought the top. I have had it for almost 2 months now. I think it's great! 10x more quiet than my stock top! The NX bar isn't nessessary unless your jeep sits outside 24:7 in rain and snow. I have yet to put it in. The sunrider feature is much easier to use over the stock top. The safari feature is great on a hot sunny day and doesn't flop around in the wind like i thought it would.
It is much more difficult to put the windows in than the stock. I have found that sometimes it is easier to zip all the windows together, have one side in the door surrounds and on the other side pull on it and connect it into the door surrounds. You get more leverage that way instead of having to pull both pieces together and mess with the zipper at the same time. Installation is probably the biggest downfall of the top; still, it is defiantly worth it. However, that is the downside to any frame-less top that fits snug and isn't sloppy looking.
My header bar had a 1/2" gap between the windshield and at high speeds the wind made it sound like my A/C was blowing on high. I called and they sent me a knew one. Haven't had a chance to install it yet. It wasn't packaged right and my side windows got a big crease in them that still hasn't come out so I am in the proses of getting new ones sent to me also. ...I need to follow up on that again.
All in all a great top but a slight wrestling match to reinstall the windows. No regrets for me.
