I have had their TTC450 CNC for over a month and still cannot get it to work. Support has been decent given all the problems I've had.By far the biggest problem is assembly. It has been a nightmare. Their manual and YouTube videos have been mostly useless.Not all the parts came at one time. Some of them have failed. They do stand behind their warranty, but you will have to take photos or videos of the problems. It all takes time to resolve. Ideally, it seems like a reasonably solid product, but some of their wiring connections are problematic and can lead to damage if you don't add some tweaks.It would be a better experience if they had an assembled or partly assembled version.
