We're thinking of ordering some more of these as well. They've performed pretty well.

We've had no luck with the spiral type, but these band type are better. Lots of choices. Pick your poison.
I have something similar and find them incredibly hard to open and close. I have the ones Fred mentioned, and do like them. It does require two hands to get them on for me.Wynette turned me on to these (locking bands)
