diymore 6DOF Full Metal Robot Arm Mechanical Robotic Clamp Claw Kit Robot Building Kit with mg996r Servos

Everything fits and work. Parts fits together. It's not proper lab arm but for education and fun will do. Instead of proper servo brackets bearings I get set of washers. I had to buy extra set of bearings for £10.

Article arrived in time, adequately packaged, no damage.The instructions included are reduced to fit on an A4 sheet, so I had to look online for an enlarged version, and then for youtubes and web guides from other users who had figured out how to put the thing together, as the instructions are at times ambiguous and incomplete. Some parts (the plastic servo arms and fittings) were missing according to the parts list on the printed instructions, but they are only used briefly to set the calibration of the servos and I was able to do this by other means. I now have the arm fully assembled, and ready to test. My initial efforts haven't been successful but at this point I'm blaming my position on the learning curve rather than any issues with the kit... will update further in due course. I've thoroughly enjoyed the adventure so far, but it's certainly not an out-of-the-box experience!

It's not very good at all. I'd say build one with Lego or buy a plastic one if you are budget constrained.

The product comes without any power pack or controller, so it is basically a hard to assemble paper weight. I have tried to contact the vendor several times to ask what additional kit needs to be purchased to actually make it work, but they have completely ignored me. One star is generous, but Amazon doesn't let you give zero.

Very good value... however, the packaging of screws and nuts should be in tandem with what is in the instructional manual.
