We ordered a couple Tumblers online on a separate site irrelevant to the reviews. One lid and a straw came back damaged and were worried if products on Amazon would fit properly. So these reviews are for the shoppers with those concerned.The red and green bottoms are silicone, as stated and they fit perfectly. Prevents cups from moving around and danging against surfaces when placing them down.The lids fit perfectly and are more sturdier than the lids that came with the cups.And the straws are 12 inch, fits great into the lids, were bought from a different seller on Amazon. Thick plastic and reusable. Also pretty and works with any themes you might like.All items shipped quick with no issues or damages. 5/5 stars from us, Highly recommend

These fit just right. Keeps my Stanley and my tables scratch free! Easy to put on and remove to clean. I purchased the clear, which isn't really "clear", but it matches the white color of the lid so it looks really good. Great value and having a 2 pack so there is a spare if needed is a plus. Recommend this purchase for sure!

Functions well to keep drinks stable. Dies not seem to allow liquids to seep in. Holds a firm grip on surfaces, especially slick ones. Perfect fit for both my Stanley cups. Attractive design that happens to match my team.

It fits my 40 oz just right, no issues and I would buy again

Durable, easy to use, fits perfectly on my 40 oz stanley. Does not have to hold liquid so not worried about leaks it slips on the bottom of my stanley easily and keeps it from slipping off the surface of tables and counters. So it function as it should. Not sure it will be dishwasher safe or not yet.

Beautiful color. Dishwasher safe. Durable and protects the bottom of your cup. NO NOISE WHEN YOU'RE PLACING YOUR CUP ON A TABLE!!!

Great accessory! Love the hint of glitter in the color. Great contrast with my lime green Stanley. Helps to not slide or make clanking noise when you set it down. It fits perfectly in cup holder and doesn’t get stuck. Would highly recommend. Easy to put on and take of when cleaning.

Ajustan a los vasos. Cumplen su función.

Le quedo muy bien a mi stanley de 30oz. Material resistente; en relación al precio lo recomiendo y ayuda mucho a que no haya fugas de liquido.

Llegaron en tiempo y forma, si cumplieron con mis expectativas y buena relacion calidad precio

El spill stopper ajustó muy bien a mi termo de 30oz versión H2.0 y la funda protectora también

Me gustaría mucho, queda perfecto en el Stanley 40oz
