Kohler 1 piece Rialto toilet ok performance?

I bought a Kohler Rialto 1 piece toilet from home depot. I bought it because my bathroom is very small and I wanted a small toilet. I am afraid to install it because I have no info as to whether it flushes adequately, and if I install it I can't return it. Does anyone have experience w/ this toilet? I am a homeowner and it will not be used commercially. I read Terry Love's toilet report and did not see this toilet on his recommended list.

Thanks,

The Rialto uses the Ingenium flush (that means it has a standard 2" flush valve with siphon jet flush)

This model toilet normally performs on the lower end.

I do remove my share of them.

Some of it depends on homeowner usage.
Some people are tougher on these than others.

If someone were to get something similar to it, but with better performance, it may be something like the Toto Supreme MS863113
