This is a great addition to the Jeep Wrangler 4 door.Product Quality: The fit is good and overall quality is extremely sturdy. The spider balls work well and after having this installed for the last several months I have seen no issues with the elastic failing or stress on any of the grommets or shade material.Use: When driving with the top back it seemed that the sun was always shining directly in your eyes. The real nice part about having this Spidershade is that you still get the feel of having the top back, but with out the direct sunlight. When parked it is really nice knowing that the interior is not getting baked by the sun! Additionally, there is a noticeable positive difference in wind decrease in the cabin as well. This seems to be very favorable for the wife and teenage daughter who both have long hair.Installation: I originally installed this with the soft top in the retractable mode (half back) and not all the way back (with windows out). By doing this I found that I was not able to pull the Spidershade back far enough and there was a little slack in the tightness up front by the windshield mounts. I would highly recommend that you put the top all the way back and then install the Spidershade (which is the recommended way). This will make it much easier to install and will help ensure that you have it pulled over the rear roll bar as it should. I leave this on all the time, soft top up or off and find it has no interference in the cabin (6' 3" and my head/hair does not touch the shade ). Note - you do have to remove the left and right windshield mount Spiderballs to secure the soft top latches (center mount always attached), which is only a minor inconvenience. [...]Overall - great quality product, very easy 5 minute or less install that adds some additional driving comfort to the Jeep Wrangler.[...] Thanks! :)
