The stuff they sell is ok and delivery wasn't bad bearing in mind it was sent overseas. However, if anything ever breaks. THEY WILL NOT HELP YOU. Last year I bought a 3D printer from TomTop. It worked fine for about 8 months. In November the printer started failing. The print bed temperature was fluctuating wildly and the printer software kept crashing citing a thermal runaway. TomTop spent the next two months getting me to run various tests on the printer, most of which involved opening the thing up and taking voltage readings from various components. I'm pretty sure they were just trying to scare me off. At the same time I was speaking with Creality (the manufacturer) who were equally useless and getting me to perform pointless tests. Eventually Creality agreed that it was the motherboard that was at fault and that TomTop should replace it. I relayed this to TomTop who then repeatedly asked me for the serial number of the motherboard. Despite me telling them over and over that there was no serial number on it. I sent them multiple photographs of the motherboard showing the lack of serial number. This carried on back and forth for a few weeks. They were deliberately obtuse and using the language barrier to evade any questions or to properly respond. Finally in late December they agreed that they'd send a replacement motherboard. When the package arrived, it was a 20p thermistor (which incidentally was the first thing I replaced when the printer started playing up) and not the motherboard. They're now not replying to my emails. So now I have a broken printer and I need to buy a new motherboard myself. TomTop is a dishonest, deceitful and petty company. If you're buying anything that could possibly require any kind of after service, go somewhere else. They are not worth it.
