Here is a new faucet wrench we just listed. I have tested this for several days now and it works very well. Also very affordable, so you can leave it on your regulator. Comes with a pin to secure it to regulator. It is extremly well made in Germany. These are only $2.49 cents! See photo in next post, I had to upload photo again due to mistake.
