Works just as well as the very expensive brands. Does not charge wirelessly like listed in item description. I will update my review in a few months to see if they will break in more and give me the comfort I have come to expect from Birkenstock. " I would highly recommend these CROCs Literide sandals. (I only used the elixir and oil on my scalp. you can do better. ) They are comfortable and well-made. I look forward to more TT products in the future. So Ive chalked it up to this being a common thing with dongle. Very pretty pink color.
