Very easy, shipped early. Excellent, top quality. I have not installed yet but very impressed at first look.

Hitch is very nice, well made, pretty straightforward to install. Final installation is indeed stealthy. I do have a couple of comments about the installation. One point about removing bumper is that directly under the tail lights are a crushable plastic mounting part. A guy that has a video on YouTube stated you have to remove the two nuts that hold this on to remove the bumper which is very difficult because this is mounted to the car prior to the bumper going on. This is not true as the bumper will separate from the part, but there are 4 or 5 fingers that have to be released for the bumper to come off. Not impossible, but I think they are designed to not come apart once assembled. I used a large screw driver that I twisted to lift the plastic while pressing the finger down until the lip disengaged. Second recommendation is the power source. Instructions require running a wire underneath the full length of the car and attaching to the battery. The GLK has a secondary fuse block under the rear floor that has numerous open fuse slots. I suggest utilizing one of those with a fuse tap for the power. Fuse 89 is for the factory trailer hitch.

Our GLK factory 1.25" hitch couldn't handle the larger rack required to carry our Cycletes. Tried aftermarket 2" hitches and was disappointed with quality, fit and function UNTIL we found the Stealth Hitch. Now we have a solid, level 2" hitch that works perfectly carrying our Cycletes. The Stealth feature was a welcome bonus as the 2" does look a bit ungainly when not carrying our Cycletes. To top it off the product is made in USA by a responsive company shipping directly giving those that choose to buy one excellent value! Thanks Steve - Job well done!
