With the Black & Decker GTC1843L20-QW you kill two birds with one stone. It's not just wireless, thanks to the 18-volt 2.0Ah Li-Ion battery, but it's also telescopically adjustable between 1.3 and 2 meters. On top of that, you can tilt the head to 5 different positions, allowing you to use it both at the sides and at the top of the hedge. The double-handed switch ensures you never start it unintendedly. The soft grip handle and the diamond blades reduce vibrations, ensuring you get just that bit of extra comfort, which is very welcome, especially when working long periods of time. In short: get yourself the GTC1843L20-QW, that way you give yourself a wireless and flexible range when trimming.
