Looking first at the Detailing Rig (Model #52810). It comes with all the necessary components in a box:
I used a soft mallet, blade and Philips screwdrivers, 17mm wrench and socket, to assemble following the easy to follow graphic (only) instructions. It took under 30 minutes to assemble.
The only thing I would recommend Mychanic add to their graphic instructions is in the third assembly step: to make sure the holes are lined up in the bottom tray with the frame holes, before tightening the four “A” 17 mm bolts that secure the two halves of the bottom tray. I found the holes were fine on one side, but slightly off on the opposite side. If they are off slightly, you will not be able to fit the studs on the wheel assembles through both the frame and the attached tray.
The assembled Detailing Rig is extremely well constructed and thought through. It lists a 350 pound/ 158 kg capacity, and country of origin being China. It comes with a one-year limited warranty. It lists at $109.99.
The Detailing Rig comes equipped with a number of useful options including the nicely sized soft wheels, lots of storage under the seat, spray bottle hanging racks, a wash bucket with removable grit trap tray, and of course a bottle holder. I particularly like that the seat can be lifted off of its studs and put on the floor to use as a kneeling pad. Very useful for working on the wheels, etc.
I found sitting on the unit a perfect height for detailing cars, as you roll effortlessly around the car.
