Product review (5 stars): Great travel potty!
We have been using this for about 6 months now.  Works great!  Folds down very small for transport.  Even used it in the bathroom on an airplane! Though it is a bit tricky!  Fits down in a little bag that we pack with extra diapers, wipes and potty bags, so we don't always have to take the whole diaper bag in the restroom with us.  We even use a little puppy training pad beneath it when using it in the car, just in case there are any accidents, but so far we've had none.  We use regular, cheap, gallon size, zip food storage bags with this, these do not fit very well, but since they go under the rim, we've had no problem with them.  We just use it as a regular potty without the bag when staying in hotels and dump into toilet and wipe out as with a regular potty seat.  It can unscrew if you turn it too far, but have just learned that when you see 3 lines on the white part that twists up, that's where we stop, so we don't have a problem with having it come apart.  Have had no problems with a boy using it as we make sure he is situated properly on the seat
