I was really happy to see the quality of the arm rest's finish.  It looks like it came out of the same factory etc.  The correct black finish and the correct red piping stitching all matched the interior of the car.  The only down-side is that the packaging didn’t come with any instructions, but this wasn’t a problem with access to the internet to download and print-off the 'official' Toyota manual - ie how to measure up, drill and insert the arm rest...  I took my time and under 1 hour it was in and my partner didn't even realise that it wasn’t there in the beginning..  The biggest sweat was actually drilling the plastic  - as stuff that up and , well ..  you get the picture.  Measure twice and drill once…  You will need a 5mm and a 8mm drill bit (and a drill, of course).  The supplied screws also aren’t the standard head, but shouldn’t cause any problems for a ‘normal’ (ie non-Philips head) small screw driver.  8 screws on all…
I reckon that it finishes off the console as it should have been from the factory! A standard item - not an optional extra...
Well worth the buy and I am very happy with this mod 
