The first day I got it, I took it out for a 3 mile run to test it out. Very pleased with this mat. Nice item just too small width wise for my granddaughters wide feet. The toe bed will be too small for those with average to wide feet. They get a lot of wear and tear. (en especial sus fundas para celular), me decidí por comprarla a pesar de superar mi presupuesto . I am very pleased with the sound I get with these. hahahaWell, for the price you pay, its worth the investment. I only have one imperfection. I was eyeing this shelf for our newborn daughter?s nursery and decided to get it for the corner for organizing her books and Knick knacks.
