Can the sliding mechanism on the (30oz) lid be disassembled for washing? My milky tea gets inside and is starting to get crusty/flaky...

I have the older version of the lid too. It usually comes out clean if you put it through the dishwasher but needs a good shake afterwards. You can also try holding it sideways under warm running water for a min and then vigorously shake it over the sink. Try the other side and repeat. Do this with the lid closed and opened.

Is there a way to keep the straw from rattling around? I use it in a quiet office and it so noisy.

You can get silicone bumpers that slide onto the straw on either side of the lid, to hold the straw in place and keep it quiet. Some products even come with tips as well as bumpers, in case you don’t care for the metal straw hitting your teeth. Amazon sells them. I have had zero rattling since I started using them, and I enjoy the tips, no burning your lips on a hot straw.

Just got mine in and I love it. I can tell I’ll need more straws so what size should I get? I like the wide straight one. What size is it?

I have a 40oz Beast which I love. I use the metal extra long straws, however, the regular size metal straws can work.

Can u use this cup without the straw

Mine has no vent which makes it difficult to get much liquid out. I’m considering returning it as I don’t like drinking out of a straw.
