I have the SATV lower doors... my wife and I installed them, took about five minutes or so, per side. Very pleased with all the SATV stuff I have bought so far.
Can't speak directly of the lower door inserts, but in the Jeep and 4x4 world Rough Country is bottom of the barrel cheap China crap. The SATV lowers fit well and look good and as a bonus USA made. F**k China!!
