I didn't find the instructions that easy, I'm afraid. I think it is presumed one knows how to loosen the lines and I did not realise (until I had lost one of the black rollers somewhere in the weeds) that once you had nucleated it the line WOULD pull and thought you had to take it out of the end.. I have made do with a metal bold holding the line in the end. Similarly, it does not seem to state if you should tighten the line with the roller in the lock or unlock position ( I presume unlocked) and it's hard to see how much line is left on the drum when you tighten when you are 8 meters away! Also, I repeatedly asked if I could use an existing Hills attachment to attach the bar to but didn't get a useful reply ( in the end I found you couldn't ). Too early to say how good the product is- ask me in 5 years but seems well made. My ratings are therefore based on ease of set-up.
