My locks arrived yesterday thanks to 2-day priority mail shipping. Install took less than 2 minutes total for both sides. Took me longer to collect the tools I needed, walk out to the garage, walk back to the house, and put away my tools than it did to actually install the bar ends. List of tools needed: Channel locks, 5mm allen key, tiny allen key that came with the locks. Haven't tried them yet but I see no reason why they shouldn't work as advertised.
