The device is very good, I will not repeat what has been said by previous comments. However, the offer reconditioned Amazon is deceptive. She suggested that only the packaging was damaged, and a counselor had explained to me that the product could only have been "tested", but not used as such. He also guaranteed me it was guaranteed as new, which is apparently not the case. In truth, the product already had more than 1,300 trips, which for me is a step above the simple "test". Disappointed by Amazon to whom I had no complaints yet so far.
