This thing is a great, high quality product. They give you tons of extra parts like air filters, mouth pieces, screens etc. it heats up in just a couple minutes, and really makes your herb last quite a while with how efficient it is. Only remotely negative thing is the fan is pretty loud when you turn the blower on after it heats up. Other than that, itâ€™s perfect. Not sure itâ€™s necessary to spend the extra on the digital model. The analog one works great and the switches and knob are real solid feeling.
