Great for my projects! I'm prototyping several microcontroller designs involving positive and negative/vacuum pressure. The quick connections were a really pleasant surprise. I didn't expect them to be reusable - after several dozen reconfigurations, everything is still tight and capable of holding a vacuum. You need to make sure the cut is clean - an uneven or angled cut is not safe. I accidentally mixed up some lines and smeared them with silicone oil and it didn't seem to hurt anything (but I wouldn't recommend it). . I was also able to route electrical cables in an air tube under vacuum and maintain a tight connection through their male NPT thread connectors. The value of it is just amazing. It's only a few dollars more than the cheapest handset, and the ports are $25. I use a lot more connectors than I expected, they're really simple, safe and reusable. The only thing I'm looking for is exactly the same set but in 3:8 format. I see a kit with no threaded connectors and a shop kit that has more stuff than I can use.
