Review on Toilet Tank Flush Lever Replacement: American Standard, Straight Arm, White - Upgrade Your Bathroom Functionality! by Eddie Orrell

Some reviews criticize it as "cheap" or unreliable. But that's the same quality as the big national retailers. I just installed this and it works great. I can't say how durable it will prove. But don't shy away from it for fear it's fragile. A CAUTION is that the lock nut was very difficult to remove to install the lever - it was screwed on very tight. But thanks to patience and constant effort, it is now doing the job it was intended for.
