First light was returned as it looked like it was opened, battery was dead and inside the remote. Just got the return item and battery is dead inside the remote but full of corrosion and there is no manual in this one. If I pay for a new battery I can't remember the steps from the first light to sync the remote to the base (It does not come synced). Honestly this is the first thing I have gotten from Shoppers+ that I have had terrible luck with, twice. The light itself though is bright and the modes are nice but I was really hoping for a working remote. I would also love a manual if a pdf version exists please as I need to clean this remote up as I do not want to wait longer for another swap.
