To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Hi Vendor, I received this item on Sep 18th. I bought this as a birthday gift for my son. So yesterday when he opened the item it is not working. Unfortunately, we missed the return window period. The pen can power on. Then followed the instruction to load the wire. It started pulling in. But after that nothing happened. I would like to get the issue resolved. Plz advise us, is this item faulty or we missed some steps in following the manual. Plz help to resolve.
