I have got to say the machine when working is mesmerising , it takes just over 4 minutes to complete the job , changes 6 bits , sprays water like a tsunami washes away the swath ,makes hardly any audible noise. Thanks for the comments guys, but I have to admit there’s something manly about the machine , it sort of makes you feel good, you have a I suppose ,control over the thing that does your will and in a very powerful manner.. hey. whatever, it’s just a machine lol
