Exact match, fixed the toilet problem

The standard flush mechanism for the toilet is a two piece, loose fit design which tends to separate from each other frequently resulting in the flush valve failing to activate. It was very frustrating having to remove the lid and reconnect the two pieces every day. With this unit, the cable trigger is easy to install, a 10 minute job at best and has not failed yet since being installed. This was an additional cost as after market equipment but I think Flushmate should make it a standard piece of equipment, even if it adds to the original cost of the toilet system. I should have purchased this in the first place and saved myself a lot of frustration. Highly recommended.

Much better handle & flush mechanism than the standard flip one....easy to install

Cable seems to be the weakest link and you can't just replace it alone so you have to spend way to much on the whole kit. Please fix the weak cable connection.

I was staying in an apartment with a toilet that uses one of these mechanisms. The handle was broken, so I had to leave the lid off the toilet so I could flush it. It was easy to install and works perfectly, so I'm flushed with pride over my plumbing skills.
