Koogel Tumbler Replacement Lids,4 Pcs 30oz Spill-proof Splash Resistant Lids Covers for Tumblers Cups

This lid design appears to be a great fit for all of these 20 and 30oz stainless tumblers. The pictures and product match. From there, installing them on a cup immediately reveals the problems with a total seal design. The catch for the vent hole and the drinking port is very difficult to open. This results in a two hand operation and significant frustration when trying to use unless you have nothing else in your hands and are in a position to get both hands to the drink container.Once full of your favorite beverage, the total seal design does not allow for ANY venting. as a result, cold beverages that contain any carbonation will over pressure and push the lid completely off of the cup. This makes for quite a mess if you are not paying extremely close attention to this assembly. I know, I know. Why not just keep the soda and fizzy drinks out of it? The problems don't stop there.In their infinite wisdom, they installed the vent port directly above the drinking port and not towards the top of the cup as is the case for standard lids. This is surely to allow one closure flap to cover both ports. This is a great idea in concept, however, once a drink is contained in the space, the location of the vent port restricts the flow of a beverage quite effectively. The designers need to either increase the size of the port to assist or, more effectively, need to relocate the port to allow air to flow in, and liquid to flow out.With pouring and storage out of the way, we can move on to sipping ergonomics. The lid has a very robust shape to ensure it locks in place. While I am certain that the designer spent considerable time trying to get this part to play well with the lid, the result of that shape makes it difficult to drink from the container directly unless you have no nose, or perhaps enjoy drinking out of a sideways cup. Neither of these is preferable to just having the lid slide out of the way or disappear when trying to drink from the container.I gave the product two stars instead of zero because the total seal design is good for storing non carbonated liquids which will be dispensed into another cup or container for consumption. This is not as intended, but is a suitable alternative use.Avoid these.

I was pleasantly surprised with how nice these lids are. They fit perfectly on the "Feti" I purchased from W-mart. With the lid snapped shut they are leak proof. The lid is well made and it's nice thick plastic that should be plenty durable. The locking mechanism has a nice snap to it, but it's easy enough to operate one handed. Considering a set of 4 costs less than 1 name brand lid this is a fantastic purchase.My only complaint is that the flipping closure doesn't lay flat when opened and my nose hits it. Not a huge issue, but it might bother those of you with larger noses.Word of advice, make sure you leave the plug unsnapped when putting the lid on (or taking it off). Since the air vent is under the snap you will be fighting the air pressure when trying to put the lid on.

I've been looking for a lid that will keep beverages from spilling out of my Rtic, Yeti, etc tumblers for several years. This product does exactly what it states. The seal is excellent. It seals so well that you have to open the latch to put it on. There are times when a hot beverage will gradually push the lid up, but if you keep an eye on it there are no worries. You get 4 in a pack. I gave one to my brother in law and kept the rest for my wife and me. Definitely, something to pick up if you're struggling with keeping your freshments from spilling while you're on the go.

This lid has a very tight fit, which is good to stop leaks unless you fill the cup a little too much, at which point air displacement will cause liquid to spurt out. The tight fit can also make it a PITA to remove for refills. You can't use a standard, unmodified steel straw as the opening is just that bit too small. You can modify the straw by crushing it slightly with a pair of pliers or better yet, a vice. Or you can take a file and enlarge the sipping hole but that will compromise the stopper latch - better to crush the straw if you want to use one or just use a plastic straw.

Cute vibrant colors with a nice tight seal. I use mine for my ice munching addiction but if you plan on actually drinking out of it the pop top that covers the drinking hole is a little bulky and doesn't accommodate your nose well causing your lips not to seal around the rim fully and the drink may spill a little. I've inadvertantly tested the durability by leaving my cup on the roof of my car while backing up. The cup landed directly on the lid and I knew it was smashed into a million tiny pieces but there was only a small crack. I was pleasantly surprised! When I lose these like the originals I'll definitely repurchase.

These really work!!! They fit snug into my 30 oz stainless steel double walled cups and the flap is will aligned and very snug - AND THEY DO NOT LEAK!! I have bought numerous other styles claiming to be spill and leav proof that were not. BUT THESE really do work and a value pack of 4 for this price, I am very, very pleased.

I've had these now for a few months. I take my tumbler everywhere and have never have a leak. It is easy to open and close the lid. I would buy these again.

Bought these to replace the originals for my Artic 30 oz cups due to the rubber seal rolling and not sealing anymore. These are great replacements. The only thing I dont like about them is the pop up top will get sticky if you drink tea like I do. So when you go to take a drink without using a straw the sticky is now on your nose.
