No es un modelo portátil debido a su sistema de ajuste con elásticos y diadema retráctil, pero se adapta excelentemente a la cabeza salvo cierta incomodidad para los que como un servidor tenemos poco pelo (por eso le he creado una funda lavable), no está acolchado y es cuero sintético. I got my hands on it and tore the wrapping open to reveal its full splendour. I prefer wide shoes but did not need it with these. A great product that solves the age-old problem of banging nails into and/or (in my case) having to drill concrete walls. Ive bought these same boots multiple years now for work. But Battery life is great, and downloading MP3 songs onto the headphones was easy. Neck is another hit or miss- too tight too loose. These won! I must admit I have only had this mouse a few min now, but here is what I have learned:- Really comfy for my hand. These are very light and comfortable.
