DOITOOL 5Pcs 3.7In Stainless Steel Cup Covers for Drinks Mug Universal Lids

Great product. Slows cooling of hot drinks. Reduces drying of residue from chocolate drinks making cleaning easier. Suitable for range of cup and mug sizes. Makes open cup less accessible to our enterprising dog.

Good product; timely delivery

I wanted to try these due to the silicone ones trapping even air out and you get a musty smell in hot weather quickly. These fit my big coffee mugs and glasses and work perfect to keep flies and nats out of my drinks. What I didn't like was the effort to remove the stickers. I soaked in alcohol over night thinking it would be a breeze after reading others complaining about it, nope - still had to use goo gone.

Seems like it'll do the job, but but as other people have commented, the stickers are no joke. Going to take a wall to get them off. But the Real issue was when I opened the package. The rim of the lid is so sharp that it cut me.

Works great at reducing evaporation so if you use with cup warmer coffee stays fresh longer. Clean easy and sturdy enough for my granddaughter to use as cymbals haha

You can use these on any cup. I like them as they will keep your beverage hot, more so when you use a cup warmer.

I liked the product, well made but removing stickers on each one of these was waist of time they stuck it with crazy glue, unless they remove it & send it , I would not recommend to buy this product, reason for me giving 1 star

These are great! But yikes to the stickers stuck on the inside. I soaked in vinegar, hot water and dish soap, bar keepers friend. Finally the bar keepers friend started to work on the 2nd application. Took 3 applications to get it off all the way and one of the lids just wouldn't come clean so I threw it away. Otherwise good product 😅

Super effective in preventing cats from dipping their poopy paws into your cup.

I’m in the middle about this one. It does the job and it doesn’t . So I love it and don’t love it. It covers my drinks yes, but if you move the cup it’ll fall off. So I wish the rims were a little more steep.
