And indeed, also the Bosch Cordless Grass Trimmer ART 26 LI is pleasantly quiet, even very low. So I would have not entered into judgment. As would be definitely her neighbor who is puzzled about where is the string to your lawn trimmer. :-)
In addition, the Bosch ART 26 LI is very light and therefore quite tiring to use in the garden. Sometimes even, without roll out each time with great effort the "string". Since gardening is fun.
But let us come now to the disadvantages:
a) A battery is a rechargeable battery. The will eventually -depending on the intensity of Nutzung- empty. For me this time is rule of thumb for 30 minutes. This time, however, I often reach not because I use the device regularly, and my garden is manageable.
b) The Bosch ART 26 LI used to cut small, thin, unassuming, red (plastic knife). If the strike a stone or a brick wall, that's it. Those things just break through. However, they are easily and quickly replaced without tools.
This issue report here so some reviews. I have therefore asked me before buying, whether I should immediately order the replacement blade. The answer is "No, you do not". Bosch provides two packages with a 10 piece plus 2 units in replacement blades hold the device.
Why Bosch knife from unstable plastic building? Well, I think that has very clear safety reasons. Real metal would definitely durable. But if a metal blade breaks and flies through the area, then I'd rather not be in the vicinity.
My Opinion: A nice piece for cordless edging in the allotment garden. Although the Bosch ART 26 LI unexpectedly powerfully goes to work, you should rather avoid large and complicated requirements to a different solution. But I give it 5 stars because I am absolutely thrilled.
Safety Tip -> Despite built-in safety measures they should use the equipment wisely, taking into ideally some goggles. The ART 26 LI is not a toy and therefore by no means the reach of children.
