My experience as a shop mechanic is that those liners aren't worthwhile. It only stayed in place for you because it had somewhat adhered itself to the tube. Until and unless it does that, it has a tendency to shift around, especially when pumping up the tire. I can't tell you how many tubes I've changed for customers who had previously bought tire liners.
