"always a pleasure doing business with greenbuddah, good response time and he lives one city over from me so the packages always get to me really quick. i had initially bought a set of these a few months ago and left a bad review bc i bought them not knowing they would be too long to properly fit into my rig (a little 6 in. recycler), more my fault than anyones, but after getting a reclaim catcher it allowed me to use these and they are a great, functional product. though for some reason, the pull of air through the catcher with these nails will put vapor into the chamber like normal but then pull most of it right back out. idk i guess thats just the physics of it. but along the way i also purchased a little zong which doesnt have a glass on glass joint, just the normal slide, but the direct inject nature of these nails fits perfectly into the slide so it can be used as a rig, which is quite cool having a zong as a rig bc of this coincidence. definitely a good buy and definitely worth it."
