@hello_marley , I have talked to their support. They say that they do not sell a tool to open their Flics, which is a shame because I have 2 of them that I can't get opened. I have even tried to use a pair of needle nose pliers and I still can't open them. I am dreading this because I have like 12 of them throughout the house and am just dreading having to throw them away when their batteries die.
