Installed one of these in my home to replace older water guzzling ones.  They look great, installed easy, and work great.  I bought this one for our child's bathroom.  I would definitely recommend a round front for potty training.  
I was worried about flushing power, but I have had no problems clearing waste.  Honestly, I barely ever use the 1.6G flush.  The 1.1L does the job 99% of the time.  
Best part is they qualify for $100 rebate from So Cal water!
