We've been using our 50w Epilog Helix 24 for about 8 months now and are starting to get asked about cutting thicker material (wood, acrylic, etc). Has anyone had experience with these aftermarket air assist nozzles that claim to increase your cutting ability by directing the air in a "jet stream" where the laser is cutting? It seems like a logical thing but I don't want to mess anything up by using something that isn't really recommended.

These are the two I've seen:

The design and principle makes sense to me, but I'm leery of buying something non-standard for my laser. I'd appreciate any info I could get!

Thanks!
