Review: Better than electrician

I bought this as the electrician did some rewiring and the shaving socket would no longer charge my Braun Oral b toothbrush (though partners shaver was ok).At first I thought it was the toothbrush and got a new one, which it did not charge either. I tried to get electrician back and on the phone he made out I was an idiot, so I bought one of these. Should have done this first as guess what both the old one and the new one, an upgraded model, work perfectly with it. Arrived quickly which was great as I hate manual toothbrushes.
