Keis Female-to-Female Connection Adaptor

The female to female adaptor has allowed me to connect my old jacket to my new gloves. I'm very happy with the result.

I had to purchase a pair of these to be able to connect my older KEIS J501 jacket to my new G701 gloves with onset of the UK winter. On third use, it appeared that right arm connector of the jacket had failed as the glove suddenly cut off. I swapped left to right and still the right side wasn't working and as these connectors were brand new, I presumed it was the jacket.
The jacket went away to the repair centre who came back telling me they couldn't find anything wrong with it. When everything was returned, it turned out it was one of these plugs that had failed.
The connection is neither tight or waterproof and as I know now, not very resilient. Frankly, this is a poor solution for connecting old type jackets with new type gloves in the KEIS range. Otherwise, KEIS riding gear is still the best money I've spent in motorcycling.
