Does this fit on an rtic 30oz tumbler?

It won’t definitely fit your new design Rtic tumbler, new vs old design? New it’s just the bear with R embeded within, the old design spells rtic around the base. The new design it’s 3-7/8” wide at the mouth while the Yeti and rtic old designs are 3-3/4”, believe me, I’ve done some research and ordered for the 4th time and I’m still getting the small lids that won’t fit my rtic new design such a pain, even with the descriptions reading that’ll fit my new design, ugh! Contemplating to buy a new cup now.

Does this fit on yeti rambler 14oz mug ?

The 30 oz magslider fits on the 14oz mug

Have anyone had an issue with the slider not working like the video someone posted?

The one in video doesn’t look like the YETI one.

what's the outside and inside diameters? My cup is not a Yeti. Thank you

Top of lid is 3 15/16", Bottom from outside the rubber seal is 3 3/4", Inside the seal 3 1/2"
