Scosche isn't the first name that comes to mind when I think quality cables for my iThings. But this product so far ( about 40 days in) is working pretty well. I use it a couple times a week with my lifeproof cases on iPhone and the Apple leather case for iPhone. Works fine with both and although the plug may LOOK big - it's a perfect fit.Construction of the unit overall is good. The retract is smooth and predictable, the cables glide in and out with no problems and the plugs are also pretty solid. My only concern is the lack of strain relief on the connectors themselves. In order to make this all fold together though, I can understand why they went without. Long term we will see.If you want a retractable cable that packs into a portable rectangle and works with all your cases though - this is it.
