I bought this item because I did not find any other surge protector with a similar rating. but they are so cute and worth it for the price! 28/06/2020 still staying strong. I took off two points off because the shoe stretch so quickly, less than 4 hours of use. The folks on the other end of the line tell me that their reception is clear. 80 mts el cable me cuelga mucho al conectarlo a mi telefono y guardarlo en el pantalon, pero sobre todo que su construccion es un poco fragil, el cable se siente muy delgado y es suceptible a los jalones. i even tried adding an insole, that didnt help. I took a screw, chopped the head off and put it underneath the lip off the bigger piece and it worked but it’s just weird that it would fit the actual rails. Klar, das bezahlt man auch ein Stück weit mit. I can see these would be great for long walks if you dont suffer too badly from foot pain though.
