Greenbrook PowerBreaker J02-C Safety RCD Adaptor

Easy to use, and with a very clear display of whether it has tripped or not. Update: A power cut of about a second just occurred, and now it will not reset. It's worked well for four years, and it's failed in a safe mode, so I've ordered another one.

Well built, very sturdy and clear to see the red lines so you knwo when you're protected. Compared to other similar items, I'd recommend paying a few extra pounds and going for this model. I've had it for probably 4-6mths now and never had a problem, and it's nice to know it's there

One star only because you dont have none ! Test worked fine but first time I tried to use it no power. Yet anything I tried it with worked without it just fine.would NOT recommend

Good value and well made. Indicator window could be clearer

Only used twice with my lawn mower seems to work fine but not let my wife cut the grass yet so not been tested by cutting the cable in half yet ;)

Good product; instructions are a little confusing.

Good looking product, easy to use and to check the status. I have three of them, but not had one trip so far which is good. I trust they will trip to indicate a fault condition if and when it happens. Not the cheapest, but I think you can buy with confidence. Recommended.

DOES NOT WORK On testing found the mains trip would go this only triped because of no current Does not do the job I would describe it in the same way as a scam. Do not be fooled by this
