Coasters by Simple Coasters - The Best Drink Coasters and Bar Drink Coasters - These Coasters for Drinks Won't Stick to Your Glass - for Indoors or Outdoors - Great for Hot or Cold Beverages (Black)

I bought these to use on the side table of my laptop stand which when combined with a normal drinks coaster, gravity and a laminated floor conspired to bring about the destruction of my favourite mug. If I had had these then it would still be with me. Thanks to the excellent design choice to leave the underside pattern free it enables the maximum possible surface area to remain in contact with the table. This means that the silicone grips so hard it will neither slip nor slide. No. You will have to peel it off to reposition it. So if you value your mug or glass then there is only one decision you have to make. Card or Paypal.

nice coasters, they do as they say. except it can be hard to see them in dull lighting. otherwise, a nice buy

Disappointing. The description says "The smooth bottom provides a strong grip on most surfaces", which I would expect to include wood - a very common table material. But no. The coasters slide about all over the place on my wooden table. They do stick to glass surfaces (I tried it on a window) but that's of no use to me. I suppose the fact that they won't stick to glasses/mugs will help, but if they actually stayed put on the table in the first place then that wouldn't be an issue anyway. Meh.

I looked a while for a coaster that wouldn’t stick to the bottom of the glass when I lifted it up, and was getting quite frustrated until I ordered this coaster which is brilliant and doesn’t stick to the glass due to a clever design, would recommend.

Well made rubber coasters, look a bit like man hole covers or something. Cling to the surface well and don't come away with the drinks just what I was after for a reasonable price.

They protect my table from hot cups, which is what I wanted them for. They are robust, and don't stick to the cup. All in all, a good purchase.

very good coasters do not move even when i pick nest of tables up to hoover under

needed on teak furniture
