I posted pretty much the same thing in the d-nail thread, I thought it belonged here too:
My sapphire spheres got delivered and I am having a lot of fun with them. I had so much fun with them I didn't try anything without them, I just did a bunch with the spheres in so I can't really say exactly how much the taste improved. It did let me turn the temp down about 25 degrees. I run around 625-635 and I was down to 600 after putting them in. It works like normal until you get them spinning, then it just happens all at once it seems like. It's kind of crazy how strong the force of the spin can get, my rig will start shaking and make an interesting noise.
I am curious if I should be worried about using a wet q-tip with them in there, aren't they more susceptible to thermal shock? Also wondering if I should use more than 4, not sure about the science behind more or less spheres being in there.
Haven't had a chance to try out my 6mm ones in my banger yet, I'm still cleaning it.
I'm really enjoying them:
They shipped them quickly and safely in these containers in bags in envelopes covered in bubble wrap in a box of packing peanuts. Pretty, pretty safe.
