Camco 20 Oz. Currituck Slide-on Handle for Tumbler Cup, Blue (51921)

Slide-on handles for 30 oz tumblers are easy to come by, but finding them for 20 oz is more difficult, especially at this price. I assume it's because the 30 oz are harder for some people to hold. We bought this one for my mother-in-law. We tested it before gifting it. The handle is sturdy and seems to stay in place well, unless you push down on the handle to fit the tumbler into a automobile cup holder. The biggest disappointment is that the handle would not fit as high on our 20 oz. Ozark Trail tumbler as is shown in the description. (See attached photo). This might prevent its use in some cup holders.

Works but goes on crooked and leaves a gap. Handle side slides on further than other side.
