Docik 30 Oz Tumbler Lid with Slider Closure for YETI Rambler Old Style RTIC Ozark Trail and More Cups, Splash-Resistant Replacement Lid Cover Accessory, Straw Friendly

work great , , glad my original cover broke

This does not fit new RTIC 30 oz tumblers.

Works okay it's just a little bulky it's hot to shep from

I'm used to the snug, loud clunk/click of the original lid fitting on. This fits ok but it's not as tight as I would like it.

If my Ozark Trail 30oz tumbler perfectly.

Perfect fit, good seal.

Does not fit my RTIC stainless steel tumbler

I must say this lid is significantly better than the original one that came with my Rtic! I also love that the sliding piece keeps the water from splashing nearly as much when I have my tumbler in the side pocket of my backpack. My only complaint is that this lid seems a little bit big for the 30 oz Rtic because I cannot push mine down all the way. So while the seal is significantly better than my original lid, there is still a bit more leaking than other reviews led me to believe. Maybe I just have a slightly weird lid or tumbler that affects the seal. Overall, I'm glad I bought it!
