I had a good look round for six months before I decided to get the L10. All the reviews rated it as “best bang for your buck” I got it from Cleva direct and got 10% of plus I got a free peg driver which was helpful when laying the Boundry wire. It says 30cm from the edges. However after a few trial runs I settled for 20cm as get closer to the edges. I have set it up and it does the rest. It does not seem to get right to the edges as your normal mower would not. However I have a battery Strimmer and does it in no time. My lawn is not the best as have a dog who just avoids it. You get 250 pegs and 150m of wire. You put the pegs in approx 50cm apart. What’s great is never having to drag the lawn mower out and find the extension. There are 4 settings - 4,6,8,10 hours and it starts at the time you set it to go. So if you turn it off the back on at 6pm it will start each day at 6pm and run for the hours you set. It goes for a charge up approx every 90mins. You need to leave a meter in front and behind so it can dock. The big question is would I recommend it to a friend or family member, yes I would 100%. It has a rain sensor on it and will return to its base until it is dry, or will then wait till the next day if it still sensors wet. It’s also a good talking point. Not that anyone can come round at the moment with Covid 19!!!. I’m going to make a ‘garage’ or shelter for it as they a bit pricey on line. Cleva do not seem to make them as the L10 is fully wether proof. Hope that helps anyone reading this. Peter
