Actually, all the problems with the evenness of the cut are caused by two reasons. The first, crazy vibration when working with dense lumber. That is, she conducts plywood and MDF normally, but the tighter lining from pine, planken from larch and so on - already with tremendous vibration. The second, flimsy sole. Just when the jigsaw pulls, you start to press it against the surface in order to somehow control the evenness of the cut. As a result, a bent sole, a crooked cut and a lot of "impressions". The price is clearly too high for such a quality instrument.
