I had to screw them to the door to get them to work. The phone itself is amazing but I cannot vouch for these modified versions. Size and lookwise MIFA A1 is better then JBL Go. 5 years old daughter. Returning them for a refund, poorly made, which is a shame because the sound is quite decent. you could just put a spacer under on the back side on the bottom but we were moving our daughter in to her dorm and didnt have a lot of things laying around to do that so we had to use 2 times as many hooks. Velcro straps are plenty long, leaving more than enough for maneuverability. The thickness of the case is good for protections and I still have the same one on my old AirPod case. Whats great is that you can use the noise cancelling in wired mode as well. I did use my own heavier anchors though.
