30 oz Tumbler Lids, Fits for YETI Rambler, Ozark Trail, Old Style Rtic (Launched before 2016) and More, SENHAI 3 Pack Spill-proof Splash Resistant Lids Covers for Tumblers Cups

I’ve used a stainless steel cup for years now and these lids are the best I’ve found to prevent spills as long as I remember to close the tab! Which I admit I’ve forgotten a number of times. My bad.I’ve purchased these lids at least three times and I did have 2 with manufacturing defects that affected the functioning of the lid. The first time I contacted the company which promptly replaced the product, no problems. The second is recently and one lid in particular, just doesn’t have the seal it needs. It seeps just a bit of water and I’m still trying to determine what’s happening. Since you buy 3 lids at a time, I just switched lids for now.Overall the seals are tight for a couple of different manufacturers steel cups, but still easily removed. I’ve dropped a cup a number of times and the lid has stayed in place - preventing a big spill. The times it has leaked is because I didn’t have the tab snapped shut. The tabs are firm and pressure must be allied to snap them shut. Some of the tabs have been harder to open and close than others, but never too hard to use. More importantly, all the tabs close and seal firmly enough to prevent leaks.They aren’t difficult to clean, but hard water & mineral deposits can build up on the clear material and you may need to brush them with a small fine brush in tighter spots. I have washed them in the dishwasher and not had problems, though it’s probably best to hand wash with hot water which I do more often.They’re not unbreakable, but it takes a lot to break one. I’ve broken just one of the 12 I’ve had over the years. They will last a long time if you take care of them. The only reason I’ve bought them a few times, is I use them everyday on my cup, take it with me everywhere, gave as a gift to my mom, and I like the feeling of a brand new clean lid every 6 months or so.

Your Tumblr is only as efficient as the top installed on it. Many replacement tops do not seal well at the dipping mechanism and allow temperature robbing airflow. Some that are well made fail in very short order because the pivots fail. These just arrived but the pivot point seems very strong the seal is amazingly tight, possibly too tight. One out of the three that arrived had a stress crack and it already I hope that is not indicative of my long-term experience. But I have purchased several different brands of tops and these appear to be the best engineered so far. Remove the gasket and soak the rest to clean with a light soapy scrub n rinse.

I read a lot of reviews about these lids prior to purchase. I have a 30oz old style RTIC tumbler and this lid fits. I will say that you HAVE to open the colored lid part when putting in onto your cup. Otherwise the air is stuck within the cup and the seal will appear to not be fitting correctly, if you tried to put it on without the lip open, remove it and open the lip, re-put the lid on, it makes a huge difference! Also, i will say that the rubber inside seal part on the lid comes off of its indented spot occasionally, it is not glued down. I am glad that it is not glued down because I want to take it off to clean it so that does not bother me. I will also say that the only downfall i see is that the colored lip does not line up with the other edge of the lid and it sticks up slightly more than 90 degrees when open. I have drank coffee from my cup with this lid on and ended up with coffee on my nose. BUT i have learned that an easy way to avoid this is by leaning your head back a little when drinking, it solved that problem for me. overall thats a minor problem and not a deal breaker for me. I have also noticed that the lids are good quality plastic, dont know if you can put them in the dishwasher, i hand wash my lids. I would say that the lid seal is really good because I have noticed that my coffee stays warm for longer than normal with this lid on and closed. I will also say that if you flip the cup directly upside down, small amounts of fluid will possibly come out, but really, why are you going to have the cup upside down?? That doesnt make sense to me. Overall some minor problems, but im very happy with these lids and love that i have more than one color for such a cheap price. i can use certain lids for certain liquids so they dont all smell like coffee.

30 oz Tumbler Lids, Fits for YETI Rambler, Ozark Trail, Rtic and More, SENHAI 3 Pack Spill-proof Splash Resistant Lids Covers for Tumblers Cups UPDATED - 7/11/18Just realized that I wasn't snapping the closure down all the way! It would audibly "click" in place when I snapped it down, but after looking more closely, I realized that it wasn't actually sealing unless I pushed it down a little further. So, now I make sure to snap the closure ALL the way down, and it doesn’t leak! Very happy with this purchase!!===Previously posted:These lids fit our 30 oz Ozark Trail tumblers perfectly.HOWEVER, we bought these specifically for the spill-proof feature, and they failed meet our expectations. We tested the products immediately after they arrived - filled up a tumbler with water and put the lid in place. It fit quite well, snug enough, but not too tight. Then came the test: snapped the mouthpiece closure shut and slowly began to tip the tumbler forward. As soon as the water came into contact with the plugged mouthpiece, it began to leak (fast drips). So disappointing!!! (NOTE: The problem is definitely with the mouthpiece closure, not the o-ring - when tipping the tumbler backwards, away from the mouthpiece, it did not leak at all.)Since we found these lids to not be completely spill-proof, I would have liked to return them. However, I have just discovered that "This item isn't eligible for return."Two stars, because the lids are still "functional" other than the leaking (but that's why we wanted them in the first place!) Would prefer to send them back. With the main "feature" not working, we really have no use for them.

Has made my various push in tumblers actually leak proof, which is essential as I take one filled with ice water in my lunch bag every day.Works great with a straw. A little tricky to drink from directly, but I don't mind as I use the straw 95% of the time.

As expected but fit kind of snug in the mouth of the cup

Good product but does not fit all that well.

these lids are very tight and no leak if over on its side , these are at the top of seal lids

One came with a faulty O ring. 1 out of 3.
