Product review (5 stars): Fantastic Little Travel Potty
I really really love this thing, which is not something I expected to say about a potty.  But, it fits in our small diaper bag and we can take it anywhere and not be rushing to find a bathroom for our 2 year old.  She has had no problems sitting on it, it's very sturdy.  We don't use th plastic bags, we just use it like a regular potty and dump it out and wipe it.  We haven't even had to use the twisting feature yet as she had no issues with using it on the lowest height.  It has been worth every penny and I'd recommend it to anyone.
