Didn't come with all of the screws, but it works.

I got this as a gift for my nephew for Christmas, hoping he would have fun assembling it. He is 11 and pretty smart, but this was a bit too complicated for him so I had to put it together. Despite meticulously separating out the screws and making sure I didn't...

Great build for a 9 year old

Loved it. My 9 year old and I cut into this project for Christmas break. It was a great learning experience for him. I was able to let him do 95% of the work. The only thing I did was help clarify some instructions, keep him on task (going through step by step) and finish...

A lot of assembly and fun.

It took me 2.5 hours to assemble and I only made one mistake. Nephew loves it. The claw is not very strong. identify and Mark all the screws before you start to speed things up.

Could have been a neat toy, probably quality control issuse.

First robotic arm took 4.5-5hrs to assemble. Assembly wasn't difficult however 2 way switches would only work one direction. Although very disappointed my son and I agreed to order a replacement. Second robotic arm's m5 switch was suppost to operate turn table function...
