Awesome toilet upgrade!  The flush and refill is fast and effective. Install was standard and fit perfectly where the previous toilet was. They are fairly heavy so make sure you have an extra hand around. They came with a wax ring and some hardware but did not include the toilet studs. I was able to save the two from the old toilet but if you think yours are old I would be prepared to replace them. Wasn’t a big deal though since They are cheap and can be found at any hardware store.
