half my dabs get wasted now.this photo is after one dab. there is so much waste every time I hit it. as you can see most of the oil gets sucked through the hole instead of vaporizing. this is because the nail is way too small on the inside.you can also see how much bigger the surface area is on my old nail. there just isnt enough space to allow the oil to move freely during a dab without getting sucked through like a vacuum cleanerterrible design.

Great
