I’ve worn them in separate rooms from my computer or phone without any interruption. Overall it’s okay for what you pay but I may look for something that fits better. This one is great, havent had any issues. The only issue is the directions. LUCKILY, AMAZON IS AWESOME. I initially loved these slippers right after I received them at the start of the winter. No response from the company. Zusammenfassend: Natürlich eine Wahnsinns CPU ! Parfait pour SantaFe XL 2015. I also bought a 10L bag that holds all my kit and it is the perfect solution for recreational rides.
