I haven't even heard of it. For many of the ones out now, it seems like they're just reinventing the wheel. Some not really in a good way. Just give me good blade options, good ergonomics, and a quality screen and I am happy.
I can see the educational and QA benefit to recording, but it's not a huge deal to me. I have capno and a continual record of placement. The image quality could definitely be better, but other than that I really like the McGrath. I think it's been over a year since I couldn't successfully intubate someone with it. I can switch between VL/DL, I have pediatric and hyperangulated blades, it's simple to use.... checks all my boxes.
