Query: Complete waste of money

We bought this product after reading some of the favorable reviews as we wanted to have a seat to take while travelling with our 2 toddler daughters.This potty seat turns out to be a complete waste of money. It is made of very flimsy plastic and the design does not fit ANY toilet seat securely. We tried it backward and forward and each time it does not stay on securely and slips around, rendering it completely useless. Worse yet, my daughters, who each weigh less than 30 lbs seemed to be too heavy as placing them on the seat caused the center to droop.This is one of the worst designed child product I have encountered.
