1. Is this a genuine branded tool?
No. This is a generic tool, not a specific brand original, but it functions the same as similar professional tools on the market.
2. Is it suitable for all snap‑on case backs?
It works on most round snap‑on case backs. It may not fit special shapes (e.g., octagonal, irregular) or very small cases (<20mm). Confirm your case back type before use.
3. How do I use it correctly?
Adjust the two holders to fit the case diameter, place the case securely between them, ensuring the case back edge contacts the holder pads. Then rotate or press the handle to apply even force until the back pops open. Reverse for closing. Avoid excessive force that could deform the case back.
