this was the link that I got it from about a week ago. If you click you notice the page is gone so either Amazon took it down or they sold out or something. It was like $39.00 and it got here in about 2 days. probably a bit steep but i live in a non-medical state on the east coast and access to better gear and accessories is pretty tough sometimes. i can't say its safe or not but this thing definitely holds its heat a reallly long time once you get it hot so you can get at least two nice dabs off of it at higher temps and even a quick low temp if you have a cap.

Edit: just checked my invoice and it was $29.99
