A little tricky on the removal of the old one. Checked online for other comments and learned that you need to cut it off. Easy install. No leaking!

Product was factory original. Longevity remains to be seen.

It works.

Had to replace original one in three yests

Good fit

This product is what I needed and it is working properly.

Easy to install. Original equipment works best.

I had a slowly leaking toilet flapper (toilet would refill for a few seconds once per hour or so). I thought, Ill just grab a replacement flapper from the hardware store or buy the cheapest one from Amazon. But, while searching Amazon, I read a lot of negative reviews where folks said that their new flapper didnt fit properly. I realized that you have to sometimes get a very specific, exact match as a replacement. I looked at the toilet bowl and it said Gerber 1.28 gpf (gallons-per-flush). Thats the first clue. Then inside the tank was printed, Replace Flapper with 99-788. So a quick Amazon search for Gerber 1.28 gpf 99-788 Flapper, and here we are. It was very easy to remove the old flapper and install this new one. 1) turn the water off and flush the toilet to drain the water from the tank. 2) unhook the old flappers rubber tabs and chain, and remove. 3) adjust the chain on the new flapper to match the length of the old chain. 4) connect the new flappers rubber tabs and chain into the tank. 5) turn the water back on. 6) after the tank fills, flush to make sure the chain is adjusted properly and the new flapper seats correctly and doesnt leak. This is a high-quality, thick, soft rubber flapper which seems to be doing a great job (no more leaking). I cant speak for longevity as its only been in use for a few days now.

Exactly what I needed to repair my toilet. Prior to purchasing this one, I purchased a universal one from a hardware store and it didn’t work.

Ive had mixed results replacing flush valves for my customers. This was an exact replacement for the Gerber toilet I needed to repair. My customer is happy and so am I!
