After I bought mine, my dad bought one for his house! It took me about 5 minutes to assemble and it came with the allen wrench to tighten the screws. - Read the other comments on these too) the screws to fasten the top and bottom plates are screwed in the columns rather than packaged separately and they are almost impossible to remove. Entweder hab ich ein Montagsprodukt erwischt oder die Qualität von BIRKENSTOCK hat enorm nachgelassen! It has a little patch of velcro so you can stick it to the inside of the case and it keeps the little bag from getting lost. You must wiggle the rack up and down, side to side and finally, if you are lucky, you can extract the rack from the hitch on the car. Honestly the mouse feels brand new again with no wobble or issues whatsoever. Has a good hard arch support & a squishy layer on top of the footbed. They stretch well and they dry up quickly if you get splashed. I did this with the lower dust cover after struggling with the upper.
