I got these a few weeks back. I went with the gray color with the double for behind the center console and just the single for front PS. The seller/maker was really fast and shipped everything with screws and even adhesive strips already attached. I love the design of the inserts. I keep one on my center console without an insert where I always keep a full size nalgene (fits perfectly). I didnt need to screw or tape on the one for the center console. It hangs very securely in place. I wouldn't recommend the double for the front PS. I think it would cover up part of the power/2nd start switch. You can definitely tell its been 3d printed (there are clear lines, and the inserts are especially a little "rough" looking). I've thought of using some fine grit sand paper on the holders. I'm not sure if the seller would recommend doing this.... For the front I got some rubber toolbox liner at sears and cut an insert that goes onto the horizontal inner portion of the center console where the shifter is. This helps minimize any vibrations from the front cup holder. I'll post some pictures. I also made inserts for all the square factory "cup holders", the area where the rectangular felt pad goes, and for inside the top and bottom of my console. If you cut the liner precisely, the rubber inserts don't need an adhesive. I just held them in front of my dash heater vents for for a few minutes to help get them straight (and not rolled).
