We have used this on three trips. 5 to upwards of 3 on a really good match. I have three pairs of the t strap thong sandals, and they last forever! It would have been greater if it were a bit more snug but I think it more or less has to do with the shape of the charging case. Its really cute and seems to be sturdy enough. Ive only had them for about 30 days and I have to do home repairs because the return window is past. The charging cable doesnt really fit perfectly with the SoundSport Free case inside as well, but it can if you try. I recently started squatting, and as I have been increasing weight, I have noticed that the base of my neck has become sore (almost feels bruised). It feels very cheap and a lot more stiff as well. If you are looking for pretty pictures and well written instructions pass on this one, but if you are even slightly handy you will be able to follow along with what they provide and install it.
