The new 105s (R7000) do look nice, and may even brake a little better than the old 105s (BR5800), perhaps because the lever is longer (please see the image on this thread).

Speaking of chains, 10 speed chains are cheaper than 11 speed chains and they appear to work on 11 speed mech and I can't tell the difference, but I am insensitive.
I ordered the wrong chair feet (soft silicone ones) for the heels of my shoes. If they wear out or off too quickly I will get some rubber chair feet instead.
