Well finished product, which has robust air. But the first dismantling of a piece of dashboard (Kia sportage) and this in order to access the unit has a switch by pressing the fate of the two tools. Just the sharp, but that's what we use most, precisely to be inserted between the two elements. So if you deposit required elements 'recalcitrant' I think this is not the product you are looking for. Perhaps the element was a bit hard (almost new vehicles) but good.
