Slyder Pro is a handheld device with a touchscreen and real temperature control. It works with any standard 510 cart and, with the Pyra Adapter, with concentrates. You set the heat in degrees instead of volts, so every hit tastes the same from the first to the last. It estimates how much you take with each hit and keeps a daily total on the screen, so you can see how today compares with yesterday. Set a target in estimated mg and it gives a short vibration when you reach it. Preheat for thick oils, adjustable airflow and a password lock are built in, and it all runs on the device, no app required.
