Thank you for the kind offer. I didn't install it and that particular brand was recommended by someone who knows way more than me.
Obviously I was concerned after watching that video, then realised it was far more likely to be down to an inferior product that wouldn't pass any safety standards.
I suppose the same applies to other electrical items that you can buy from China on ebay or in cheapy shops.
LAP are a UK company and their products are trade rated.
The actual product is tested with the following CE standards : BS 1363-2 ASTA BS 5733 EN 605950-1, ASTA
It also has very good reviews when I looked last night.
I had a qualified electrician install new light switches and sockets after having to have new ceiling lighting installed in the kitchen/dining room as the whole ceiling had to be re-plastered after burst pipe in the bathroom 2yrs ago.
Whilst he was here I also got him to replace the circuit switch box with a modern one which has RCDs and isolates certain parts of the house much better. It also means that if anything blows then its a case of flicking a switch rather than messing with fuse wire
