Produces very little reagent, is constantly crashes. Heater too. As soon as you fall below 50% of battery locks. In short a good big stew as Archos likes to do. 3 Archos products bought in 4 years, one still works. The rest went to the trash and even worse after a drive out of warranty repair at Archos 80 euro repair, the unit is returned in the same condition and I was never able to assert the rights! Too bad because I tend to want to favor this French society.
