I like this style of freezer ice cube tray: silicone and big cubes. None of that snapping and cracking.

Before a camping trip, I’ll freeze whatever I can, especially any carried water. Possible freeze a small box-bottle of Pinot Grigio and it’s good to drink in a day or two.

Oddly, packaged ice in Canada is usually shards of 2cm thick ice. I think they make big blocks and smash them up. Not like the UK.

I think I’ve only seen the cylinder cubes in the article at Starbucks.
