First off the unit is fully adjustable, it fits with the case and the pop socket on the back attached. I’d like to see the option for automatic logging of all key/button presses to track total usage of the mouse, maybe even include tracking of how far the mouse has traveled on its mouse feet so you can gauge how close you are to hitting the 250 km lifespan of its feet. This didnt bother me too much. i dont regret the purchase at all. Third, I am a size 10 with a somewhat long big toe. Will not be purchasing Chacos any more. This device does not have that flaw. Let’s say that I received those tried them on and I have not worn any other pair since. first of all i’m stupid and didn’t know my iphone could wirelessly charge. Id give these ones a swerve in future band try a different pair.
