❗ Troubleshooting

 At Paras Projects, we believe in full honesty and transparency. That’s why we’ve introduced a Video Proof System for every robotics kit order.

🎥 1. Project Working Videos

Before dispatch, we test each robot kit and record a video showing that it is fully working and functional. This helps you understand how the kit performs and ensures you receive exactly what is promised.

📦 2. Packing Videos

We carefully pack each kit, and while doing so, we record the entire packaging process. This includes showing all components being added to the box to avoid confusion or claims about missing parts.

✅ Why This Matters:

Prevents fake refund requests

Builds customer trust

Helps students understand the assembly process

Ensures full quality control from our side

We share these videos privately with each customer if needed.
