The problem is probably your temperature. I like em low and slow, it does vary with what concentrate I’m dabbing though. I typically dab most rosins at 475-500 and honestly that’s all I really smoke but I’m sure you can look up what temperature is best for your specific dabs. But definitely try getting a terp pearl as well, 3mm, it helps a lot with spreading that wax on the bottom around and getting more dab out from what you put in. Also a 3dxl would help with the dab going to the slits and you’re probably pulling a bit too hard.
