These are normally strong lids except if you drop your tumbler on concrete and even then the lid held fast but it hit square on the ring holder and broke in one piece did not shatter. Had to get a replacement since I missed the ring holder.
Does not fit my Dunkin Cup at all entirely to big! Will be trying to return the thing I have no use for it. Doesn't even fit my stanley.
I was very concerned that I was not going to find a lid that had a carry ring on it like the one I had. I had accidently dropped by tumbler and broke the carry ring. I was so excited to find it on mybevi and it fits perfectly. I highly recomment mybevi. It was very easy to order and arrived within the expected time frame. LOVE MYBEVI!
The best coffee tumbler ever purchased. I love the slim design and drinking lid. Most are huge and you end up with your drink spilling everywhere. Not this one! Love it!
