I literally discovered the STARTT 3D printer hours ago, and I am new to the game. Is this low-cost system really worth me investing in, even at the low price, or should I consider something else? My interests are limited to small items to make with my kids, and the occasional self-designed keychain thingee for family gifts, and maybe trying to make a replacement knob or something around the house. Purely simple creations, but with decent quality. Mainly I don't want to continually keep something working all the time. I just want something that is quite user-friendly for kids, and that just works. Any advice is much appreciated.
