Very Cheap Quality

I hate to give bad review but you get what you pay for. My son has issues with brushing and flossing so I bought a bigger water pick and he made a huge mess couldnt control it. I thought this would be the answers since no batteries. However filled with water and it leaked everywhere. Then he used it and all it did is give him a drink of water. Sorry but This is not good for anything but teaching a child how to use a bigger one. D QUALITY, D WORKING B GOOD FOR TEACHING ONLY
