Review on TISUR Titanium Keyring with Side Pushing Design - Stylish Men's Accessory in Keyrings & Keychains by Brian Rogers

The list of statements is "easy to open with two fingers" - they are very difficult to open IMO it took me two hands to separate the rings then you have to insert one finger to hold it open and yours attach other hand to free key.

Is it easier than a regular keychain? Yes, but just a little easier. Not worth $15.
