Weighty and handy

As someone who has been self collared for a long time, had a collar that someone else held the primary key to, and has severe medical issues, I find it incredibly important and necessary for me to have a key to my collar. If I need to, I can take my collar off safely and without any damage to such a precious item. I actually prefer the master key to the allen wrench by far! It's easier to handle.

Smart products. But a little difficult to use if you have it in the keychain with your other keys. Maybe add some structure out side the key for better grip. And maybe the key should be indside the removal part of the key chain. But still great to have with you on the road.

Problems Solved

Ordered the new, smaller master key it showed up without the logo for the company. I contacted customer support, they paid for the shipping to send it back to them, added the logo, and then send it back to me priority mail. I’m happy customer..
