Cost isnt really a barrier. Concerned over charging plug/potential water damage. The adhesion is SUPER STICKY. After using 5 months, the synchronization of stereo (A2DP, for non-communication like game and movie) is broken so occasionally there is 0. Super cute style of crocs. If you found my review helpful, please consider giving me a helpful vote. Im 6ft and have long arms and its almost impossible to find one of these long enough where I can do a full pullup and not have to bend my legs at the bottom. They want to do right by the customer, and I plan on being a repeat one, both for their quality product line and excellent customer care. The sound quality is great and the battery like is great too. Edit, to add that the seller was very responsive to my emails, and gave me a refund of what I spent on longer bolts.
