Bought this to prevent potential damage to power tools. The lanyard is quite well made, with an elasticated inner, so that dropped tools decelerate slowly, rather than a sudden halt at the end of the lanyard. The only negative points were the supplied carabiner was quite small, and didnt have a thumb screw lock.Essential equipment if working at heights, easy and sturdy attachment.I use them almost every day, even when on the ladder, keep my drill in place and always at close reach.If you want to avoid your expensive battery drill to fall down while left on top of the ladder don't hesitate get them. Perfect health and safety addition.The aluminium carabineer hook was slightly out of alignment but this was easy to rectify. Nice extensible lanyard, just keep in mind this is for small weights only (not suitable for large heavy objects, but great for securing hand / power tools).Again you look at this and say it’s something I don’t need , if you work at a height it’s a mustGreat does the job, keeps tools tethered and stops them from falling on people's heads.
