This is a conventional mower sober enough in its design. Its "tube" is not at the top of ergonomics, especially when one is accustomed to mowers more curves. by against the base plate allows the standing pose which is quite convenient. 3 clogs provided offer a wide range of cutting height, the third shoe being provided for maintenance of the beard. The scale displayed on the side of the head allows to choose settings and check it before you start. The integrated scroll wheel that allows selecting the pitch has a locking system that ensures a secure fit adjustment. The on / off button is hard enough, so no risk of inadvertently turn on or off during handling. The blades cut perfectly. Is it due to the W-Tech technology? No idea. I used to spend my men to the mower, I did not see any difference with these blades, nor the time savings promised on the box. The blades are effective, but at the same time, they are new. They are self-lubricating and easily removable for maintenance. This trimmer is used with wireless, full charge being sufficient to hold several cuts. Recharging the battery is done by a cord equipped with a jack, which is quite rare. Comb and cleaning brush are included, but there is no provision for the storage and transport of the mower and its accessories / A 3-year warranty suggests that the manufacturer is sure of the quality of its product.
