Had sold a used ASUS RT-AC5300 router to makrospec2010 yesterday, following a PM with an offer.

Deal went on as planned albeit late from his end - COD and transaction was made sucessfully.

That evening, buyer WhatsApps me, claiming unable to connect to internet while other functions were working.

I tried to assist him troubleshoot but somehow felt he was not responding on time and delaying feedback I asked of.

He replies me early next morning & cites that he tried to troubleshoot it but no avail while 2 of his existing UniFi routers can work.

I agreed for a refund; with a COD at the same location and time that day.

Following my return, I tested the routed & found it was working perfectly, in which I relayed to him.

He claimed that it was funny as it didn't work on his machine and perhaps it's a problem with his setup after I sent some real-time pictures.

I informed him that his system should not be a factor for the router not having an internet connection & that I am willing to go to his place and help him set it up, to which he just repeated "maybe my system not compatible".

He also wished me best of luck with my future prospect - making me think why would someone not agree to take my help unless he only wanted to "try" it.

Following the COD, I noticed from his forum profile status showing he was browsing for other cheaper routers (Mikrotik).

My last message was asking him to send me a picture of the BTU (modem) from UniFi he was using but he hadn't replied me since.

It's funny considering the buyer; a Chinese man in his late middle age & is chauffeur-driven in a silver E-Class (W212 facelift, license plate. 1168), can opt this way.

I missed out on another prospective buyer (offered after this guy but has since bought another router) thanks to him but I'm not gonna hold grudges due to his age although I do not wish to deal with him after this.

I hope this post can educate and warn others on what people are willing to do these days. Many sellers are willing to go the extra mile to assist or share their knowledge, as long as the buyer is honest & upfront on their intent.
