I bought our Waterpik at Costco. For $50.- (Canadian), we got a countertop model and a travel model. My husband had a PEG tube for more than two years. What I found most difficult was whenever we went out of town, we had to bring boxes of Ensure with us because he was using a special high-calorie prescribed Ensure. It was a drawback, no doubt about it. But if you can swallow, you probably will be able to travel and not have to bring a Waterpik along.
