If you are looking for practicality and reliable electric hedge trimmer, the Einhell BGEH6051 is a wonderful choice to consider. It has double-bladed cutters which are counter-rotating, to provide a very satisfying result.
Equipped with a 600 watt motor with an all-metal transmission, it will outperform a lot of the competition. The motor powers a pair of two-sided dual-reciprocating safety-blades (51cm) that are precision-ground from top-grade steel. This not only means they’ll cut quickly and cleanly, but also ensures you’ll get more out of them before they need sharpening. The blades have an 14mm tooth-spacing and produce 4200 cuts per-minute.
