JSS Wolecok Set of 2 Silicone Cup Lids Food Grade Silicone Glass Cup Cover Silicone seal lids, Leakproof lids (Grey)

Very useful to avoid spills if carrying mugs of tea, especially with tremour problems. Sadly not available now…

I bought these covers because I live in the countryside and insects can be a bit of a nuisance. Having bought some previously from a cheap Chinese site, I needed a couple more and didn't have times to wait six weeks for them to arrive. These are better quality than my cheap imports, but I still don't think I would rely on the suction power that they purport to have. They do sort of shrink into the cup if the beverage is hot, but not enough to run with the cup and not spill it. I don't think any of them would do that. But for my purposes, which is to keep the creepy crawlies and flies out of my tea, they do the job well.

I was very sceptical about this product. I'm now totally surprised how well it works! I needed a lid for my ceramic travel mug which sits in a cup holder attached to my wheelchair.Despite bumps, jumps and wheeling across cobbles, not one drop was spilt.Such a simple, yet effective design. Very pleased with it.

Keeps flies etc out of your drinks, fun product

Took a few goes to learn how to seal the cups but works well.

Just a bit more suction would be good :)

did exactly what they were bought for

I have to admit, I'm surprised by these. I had high hopes, and they exceeded them.They help to prevent spills, keep hot drinks hot (well, they slow the inevitable cooling this time of year) and generally do all that can be asked of them. Can't go wrong with them really.
