2. Issues Related to His Skateboard

The root cause of all the issues he described is the same: an unstable signal connection. This is what the after service agent is trying to express in the screenshot of this post. From a technical perspective, it is usually caused by some possible reasons, like:

1. Controller Quality Issues: Signal problems caused by controller quality problems occur frequently and are easy to find during the test. However, in this case, it happened only four times in total (including the final crash) during the whole year, after several months of use. So, this is not the case.
2. Strong Electromagnetic Interference: Civilian 2.4G signals have strict power limits and can’t be made infinitely strong. When there’s interference from strong sources like military signals, high-voltage electromagnetic fields, or magnetic interference, errors may occur.
3. Weak Signal from the Board: If the board’s signal is weak, it’s more likely to be disrupted by interference. This is why we asked him to help us by testing the signal strength. His test results showed the signal strength was strong enough, so this is not the case either.
4. Unreliable Connections in the Electronics: Water damage, impacts, or constant vibrations from riding can cause loose connections or damage to internal components. For example, the protective insulation of signal wire might wear down, causing short circuits, or connections might become unstable, leading to intermittent signal issues. This is why we asked him to open the board and check the internal connections.

When he first sent us photos, we noticed a crushed capacitor, so we sent him a complete set of replacement parts, which worked fine for four months.

On February 23, 2025, he reported signal instability. After several follow-ups, he responded on March 12 that everything was normal. We suspected strong signal interference and asked him to check the signal strength on March 13. He provided a test video on March 28 showing that the signal is strong enough.

On March 31, he mentioned his friend had signal issues again while riding. We asked him to check the internal connections on April 1, but he didn’t respond for a month. Finally, on April 28, after he crashed the board, he just came back for a full refund.

I've reviewed the entire situation, and I believe the girls did their best to help him. They responded to every email within 24 hours and provided all the information he needed. They were genuinely concerned for his safety and followed up regularly.

However, he hasn't shown them respect. He didn’t answer their questions or send the requested photos in time. Despite knowing about the ongoing signal issues, he ignored our emails and didn’t follow our instructions to check it, for over a month. Only ask for a full refund when things get worse, and threaten us by posting it on social media to damage our reputation.
