For Budget-Conscious Pros:
XTOOL X100 MAX – Nearly identical to MAX2 but lacks J2534/FCA. Great if you don’t need those extras.
For Basic Diagnostics/Key Programming:
XTOOL X100 PAD3 – Compact with decent features, but no WiFi or online programming. Good for entry-level or mobile use.
For Casual Users/Students:
XTOOL IK618 – Affordable and simple, but limited functions and battery life. Best for light or occasional use.

The IK618 is a budget pick for minimal needs.
