I found this to be a perfect piece for when you want a water cooled hit without having to use a whole rig. Gives you nice clouds with great taste.

Satisfied with my purchase. Doesn't spill when laid down. Good grip. Nail is titanium.

WOOOW IT GETS STRAIGHT TO THE POINT!!! I REALLY LIKE THIS STRAIGHT SHOOTER !!!

Works beautifully!
Delivers a smooth hit, it's sturdy, straightforward to use. Great quality so far. I see a lot of people had issues with the water, so here's what I learned immediately:
If it spills when you have it at an angle, you have too much water in it.
If you're inhaling water, you either have too much water in it, or are pulling way too hard on it.
If you take the top off to fill it, the water will come out of the bottom when you put the top on, bc it's basically a syringe, as far as design.
You really don't need the chamber more than half full of water, and really, you can do a bit less than that and probably be fine. Great purchase!

So it came with four pieces where the nail end silicon goes into the glass cylinder side where the hole leads into the center of cylinder. The mouthpiece end is the larger of the two goes where the large chamber within the cylinder. The nail is attached(pointy end outward). Then pour water just under a half. Plug the mouth end and tilt the straw sideways. If water spills out you know for future reference you poured too much water into it. Transfer your concentrate into silicon jar and heat up the nail till it turns color then dive into that jar with the nail downwards like a straw. Super compact and executes the same intake draw of the THC. Very impressed for the value. It’s worth it
