Was easy to replace and surprised additional screws were included. 5mm connector. So, if you are interested but think $100 is a bit to steep, I would strongly recommend Amazon Warehouse deals on either used-like new or used-good versions! These silky soft pjs have been going strong for months now through countless hot flashes and heat waves when it would get into the 80s in our bedroom. I did purchase insoles for extra comfort since I’m on my feet all day, and they make a difference as well! ), dont rub my heel (I get blisters so easily from shoes rubbing my heel/Achilles tendon area), are incredibly cute (people continuously give me compliments on them)! the locking mechanism was interesting. Its is a great sandal, lightweight. Entweder da hat was mit dem Umschalten nicht geklappt, oder der Kopfhörer dreht im Bluetooth-Modus softwareseitig ordentlich am Sound. I contacted support again and they told me that I would ve contacted by a special support team within 24 hours that would give me a code to activate the software.
