I use this cable to extend my extension lead. This means I can have it near my rig and far away from the plug socket!
It's a great cable, thick enough to accidental damage with blades or heavy items etc. The only downside would be, because of its thickness, it can be rather bulky and hard to store when rolled up!
Really like the cover on the female side of the cable, stops dust and dirt that might damage/break the cable getting in!
Would definitely buy again if I ever come to need one, might go for one longer than 5m next time!
