Why I think the Petzl Grigri belay device is ace and whether it's suitable for trad rock climbing

There must be a million Grigri videos on YouTube, but there's not one of mine, oh wait, there is now. It's about the GriGri but I mention a few others like the Click Up, the Smart and the Revo. I also chat about whether they're any use for trad climbing and direct belays... Link to GriGris: https://amzn.to/2KvsZJQ Please do fire away with any questions...
