I’ve been using my KerboCharge gully for almost 3 months now.
Easy to use if you can bend down far enough to feed the cable into it, would be difficult for anyone using a wheelchair though.
It works exactly as it says it does, simple to use and the cable is under the footpath so no tripping hazard at all.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
