excelente mouse solo que seria bueno se cargara mas rápido y que del 30% al 100% te lleva mas de 1 hr sin embargo fuera de eso es un excelente producto. I really enjoyed using this I also realize you can also use this to do hip thrusts with a resistance band in between the push-up handlebars. Hopefully that helps you guys decide whether or not to invest here. It looks expensive and it really sparkles! The sound from the earbuds is very clear. Purchased as a Christmas gift for my so. This product is very convenient to have and works very well with the iPhone I give it two thumbs up. 40 prevent sound leakage very well. 5 normal but they dont have this size listed. I love how the battery life is shown on case.
