My first flip! I have a huge collection of the era normal straw, and I think I enjoy the straw access without the flip more. 4 instead of five stars because I think the mechanics are a little tough and the brown isn't the deep brown I thought it would be; it looks a little purplish

These are great
The era flips are fantastic and love the lid. Do not hold ice as well as some of the competitors and shipping from the company website is slowwwwww. Like even the expedited shipping it’s like booting up dial up internet slow. Other than that great product.
