Having had previously polystyrene model almost the same price, there is no doubt that this one is the best choice. The unit is very well finished, and super accurate guidance system and easy to operate. Two complaints: the remote control requires batteries * six * LR4, which is ridiculous. It was enough to replace them with a large square stack to resolve the issue. And secondly, the autonomy of the unit is indigent, it takes 50 minutes of charging for 8 minutes! In contrast, big plus for: blades and trim replacement, bravo. The USB charging cable to recharge the unit directly to a PC or external charger, rather than on the remote control, which helps to empty the large piles speed V. So very pleased with this purchase, done our part " offers recondionnée, new- -as is "and keeping promises perfectly for a nice price reduction.
