I purchased the 20m one back in March to try to teach re-call to my new rescue sighthound. The lead is ok in that it gives more freedom than a normal lead but I found that it absorbs water very easily. So in the wet weather you start your walk with a nice dry lead and by the end you have a very heavy wet lead to hold - rather unpleasant! I found it did snag somewhat when dry but even more so when wet. I also found my sighthound would get tangled up in it and gave himself a few rope burns!
