The toilet trainer is a very good idea for small children (gift for a 2 year old). Generally I find the toilet coach very well, but I can understand that some people here are concerned about the plastic construction. Safe would, of course, if the whole of metal would be, so the structure would be much more stable. But first to the product itself. The structure was actually quite simple, down to the last screw. This would not let just turn in the thread itself, so it was a little difficult to fix the final stage. But the others could be very easy to turn with a 5 cent coin in the thread, while the screws could be drawn even properly fixed. I was totally surprised to find that the whole could be fix as well. Once the coach was finally built, we have set him straight to the bathroom and it worked wonderfully. The trainer fits perfectly on the toilet. And the coach has been tried immediately. , Turn up climbing on the top step and sat down. No problem. intuitive. And have fun the little ones. Problem is that they simply testing it for fun, because it's interesting. Very good idea, works very well. Only it would be nice if the whole thing even more stable. So if you had no concerns.
