5-DOF Robotic Arm Kit Compatible with Arduino IDE, STEM Robot Building Kit Programmable DIY Coding STEM Educational 5 Axis Robot Arm with OLED Display Processing Code and Tutorials

I tried putting it together a screw stipped and a part broke i was just incerted in the slot i didn't even put any pressure on it it just snapped i don't think this acrylic steardy enough for this kit aleast that one part. It should be metal maybe like erector set like peaces would be better Hardware is alright not the best. Controller board looks well buit batteries is working fine the battery hold seem to be good quality. Servo seem to be built good. Since the board is adruno board im sure i find use for it and oled display has many uses not a tolal lost just acrylic parts not thst great.
