For most retail trainers, a compact CBD vaporizer is worth it. Here's why:

• Portability: Slips into a pocket or small pouch, so you're not lugging around a bulky device.
• Discretion: Smaller size means less attention, which is helpful in professional settings.
• Ease of use: Many compacts are draw-activated or have simple controls, so you can focus on training, not fiddling with settings.

But if you're a heavy user or need all-day battery, you'll be recharging mid-training. That's frustrating.
