Has anyone tried any of the collapsible reusable straws? I first found out about them here:

Foreverables fold up to fit in a sleek keychain-sized case so they go where you go!finalstraw.com

I am not much a straw user myself, I just drink from the glass mostly, but I hate plastic straws environmentally. So I started looking around. Amazon has several options besides the one from that website. Some are all silicone, others have silicone inside and stainless steel outside. They collapse into a small carrying container of some kind and some come with a cleaning brush. I saw one Amazon offer that had 5 sets for only about $12, each set a different color.

I do like to know I have a clean straw when I travel to foreign countries though or anywhere where I don't know the history of the straw or the bottle/glass. I saw a vendor recycle a straw once and that was enough to make me want to try these.

Has anyone used any of these?

I have the Kleen Kanteen stainless steel straws from 5Gyres for home use:

And was thinking of getting the silicon straws for travel use (as I'm worried steel straws may set off metal detectors when traveling).

Good thought about metal detectors.
