I ordered the first set and liked them so much I ordered a 2nd set. I use them everyday. They are really nice and pretty and not too thin. They are flexible but sturdy. Yes they really do have suction. Most things you can pick up with the Silicon Suction Cover knob, though it isn't advisable because if it ever doesn't hold it would be a mess. I use mostly over cups of hot tea or coffee or glasses of water. It keeps warm things warmer and it keeps dust and little flying bugs out of glasses of water I always have sitting around. I think these silicone type covers are really pricy but they are worth the price. These were more reasonably priced then other ones I looked at. It took a little while to get them but not too long. I got them sooner then I thought I would.

A friend had a set of these and used them to cover her coffee cups. I thought it was silly -- until I tried it! They are easy to remove, but they hug the cup so tightly you could lift the container by this lid. (I wouldn't suggest lifting a hot cup of coffee by the lid, but you certainly could use it on a small bowl or can.) I'm ordering more!

It seems like if you bump these at all, the suction comes loose, so don't rummage around in your fridge! Not a very secure lid.

I gave this product one star so that I could write a review. Don't waste your money if you want this product to keep your beverage hot or even warm! The only for the lids is to keep out insects. Not what I wanted out of this product.

Good silicone covers for steeping tea. They hold the heat well. My only complaint is that they are a little smaller than I prefer -- they cover my cup (and it is big) but just barely. Anyway, they work great and there are four of them.

They work great! It is indeed a very strong suction-I can lift up the entire full mug by holding the pink tip! I wish they came in a 4pack of different sizes, but these are great.

These are very cute but they don't have the suction power. I tried placing it on a coffee mug, but after pushing the middle down, I noticed there was no suction power at all.

I wish I had these years ago. when I first bought them; I had my doubts. but that was dashed with the first use. I will be expanding my bounty.
