It totally fits in 3d chamber, just takes an extra heat cycle to get it above 400°.
I am still using a terpometer until I get the time for the desired temp dialed in, since the app readout isn't accurate for the insert, but it totally works and is a steal for the price in my opinion.
It's a great insert unfortunately it does not work on the new puffco peak with new 3D atomizer . The coils are around the sidewalls and it doesn't get hot enough to vapor the oil.
It takes some extra heating to get the insert to temp, but as long as you don’t mind the occasional spill behind the insert and the fact that it will drain your battery quicker, the flavor is very nice. I much prefer dabbing off of the sapphire surface vs the 3D chamber. It feels a lot better on my throat overall. Just don’t pull too hard or pack too much and it wont spill out of the insert. Once dialed in it’s a great addition to the peak. Been doing roughly 520 F for 2 mins for settings and I hot load the dab at around 1 minute or less using the oculus or bubble cap.
Works great with the puffco, giving way better flavor. Can also use it as a drop in insert.
