Came within HOURS of ordering
This is a smaller cone then I assumed it would be, these are known to last ages though so not concerned. It worked as expected. The best part of the order was that I ordered this item around 3in the morning and it arrived later that afternoon around 3pm I believe. That's insanity! So very fast! Not the 1st time Amazon has pulled off this crazy stunt. Makes me kinda worry their employees aren't getting over worked.... Sure hope not. I bet it's just they have gotten so good at what they do now and hubs/warehouses all over. I live in Portland Oregon so pretty big city known for its Tech Savvy-ness and tech inclined residents so makes sense to have a warehouse near my local stocked with things to makes insanely quick delivery times like this... At least I HOPE that's the case hah. Anyways, totally awesome and totally good item.

Wanted to try it seen u tube video
Tried it , works looks like it's going to last a long time, bought a glass coster for a dollar from goodwill and scored the inside with a diamond wheel makes a good past or slurry, the only down fall I'm afraid I'm going to knock it off work bench and break the cone

I read about this product on a facebook group for metalsmiths. Someone said it was the best so I decided to try it out. WOW! I can't believe how much my soldering results have changed for the better.

Most likely operator error
Since this is the first time I have purchased this item and used it, I can't lay all blame on the item itself, but on me. I cannot seem to get it to produce the 'slurry' that is shown on videos I have watched for instructions. I tried it repeatedly but feel this was not my best purchase. I feel sure that in the future I will attempt to try it again and again, hoping for better results. I actually do better with plain Borax , slowly mixing in the water.
