Fluidmaster 640 Perfect Fit Universal Toilet Tank Lever, White

Has a good range of adjustment and fit a side flush Aquasense no problem. It's plastic, but the old metal one rusted and failed after only 20 years, so perhaps this will be better. Seems well built. Check handle orientation, mine was upside down, but just snaps off so no problem.

Easily installed by true amateur

All plastic piece. The installation is kinda tricky, you need to assembly in a way to get the tension needed, I did it 3 times to get it properly done.

Good product, better pricing

Not as universal as it said in the description. Having changed many of these over the years although this one was a little different style I did not think it would be a problem. After a couple trys I got it to stay together but to flush you had to pull the handle up instead of down. And it hit the tank so it wouldnt fully flush. I tried 4 times to take it appart and reinstall it to make sure I hadnt done something wrong but I dont know what I could have changed. Neat idea but just wouldnt work on a side flush tank.

I was never able to adjust it to get a strong flush when I put it in a position that flushes strong, then trying to tighten it, it would rotate no matter what I used and how carefully I handled it. I have to keep pushing it to get everything flushed

Plastic JUNK! The piece that is supposed to unthread so you can actually attach the lever to the arm in the tank does NOT unthread. Invest your money in a product that isn't cheap plastic, something with parts that actually work!
