Product Description

Explore hydraulics, pneumatics, and robotics with your very own GIANT hydraulic hand! Using over 200 plastic pieces and piston tubes that you fill with water, build an awesome mechanical hand that uses hydraulic power to simulate the movements of the human hand no motors or electricity required! Once assembled, your cyborg hand slips onto your own hand like a glove, with mechanical fingers that you operate with your own fingers and that can grip objects with enough force to lift them. Challenge yourself to pick up and hold a variety of items like bottles, pencils, small items anything with reach! The hand can be configured in three ways left hand, right hand, and claw-like, with the thumb in the center and can be adjusted to fit virtually all hand sizes. A 40-page, full-color manual guides model building and experimentation and provides engaging scientific information about how pneumatic and hydraulic systems are used in industrial robots to assist with a variety of tasks in our modern world.

Great building and playing experience, but broke quickly

Reviewed in the United States on January 17, 2024

Verified Purchase

Santa gave this to our 9-year old son for Christmas last month. We had a great time assembling it together, and our 5-year old discovered that cutting the pieces out is one of his favorite things to do - which is great, because there are a lot of them. 😄 I definitely recommend buying a Micro-flush cutter like the kind used for modeling kits to assemble this. Any other method would be cumbersome. You’ll also need a very small Phillips screwdriver, but I think most parents these days probably already have one of those for toys. I loved the hydraulics/pneumatics lesson in the middle of the instructions book. The kids LOVED playing with it once assembled…but part D18 that connects the thumb to the rest of the hand broke in a matter of days. 😢 The good news is that Thames & Kosmos has a replacement part request form on their site. We submitted a request and are waiting to hear back. I’ll update with how that goes. The hand also works as a “claw” without the thumb, but the kids are currently pretty devastated. Hoping the manufacturer can help us out.

Update: adding a star for customer service. Within a few days of notifying Thames & Kosmos, we received an email stating that they were mailing us a replacement part for free. Will update to five stars if the rest of the parts hold up over time.

14 yr old loved it. Needed family's craft knife, small head screw driver, and cutting board.

Reviewed in the United States on December 27, 2023

Verified Purchase

14 yr old grandchild was ecstatic when they opened this present. They are an experienced Lego builder, but hadn't run across a project where the pieces had to be cut apart. Each color was cast in a sheet, with connecting thin plastic. For instance, all the black pieces were connected together. Same with the blue, yellow and white. Some other parts, like the hydraulic cylinders and small screws, came in plastic bags. Following the diagrams, they cut loose each piece as it was needed, and not before. A parent emphasized that it was important not to over tighten the screws.
For a somewhat younger person, an older one could act as an assistant in separating the parts as needed. Assembling the hand is a good exercise in focus and patience in following the steps. It was fun for the 14 year old to take time and tackle this challenge. It took him something like 4 hours. Taking breaks reduces stress for those susceptible.
The hand is adjustable in several ways, including being able to attach the fingers in different places. Grandchild had fun testing the hand's functions and abilities.

A lot of fun but qualify could improve

Reviewed in the United States on January 5, 2024

Verified Purchase

I think it’s a pretty good value as it kept my 6-year-old occupied for quite a few days to put it together. He got it as a Christmas gift and immediately fell in love with it, even before opening the box. He did need some help here and there but was able to follow the instructions and do most of the assembly himself. There are two things that could be improved in my opinion. First, it leaves a very rough sometimes pointy bump after breaking off the pieces from the frame, so definitely need to be careful when younger kids are playing with it. Second, the screws are a bit tight even for me, so I ended up helping to make sure all the screws went all the way in. But overall this is a pretty cool toy and the most important thing is my son loves playing with it! If I had the choice I would give 4.5 stars.

Takes HOURS to build

Reviewed in the United States on January 8, 2024

Verified Purchase

So I’m not gonna lie, I thought this was so cool, my child had been asking for one for months. Super cool of Santa to bring one for Christmas! I figured it would come out of the box somewhat done…..(and this could have been my fault for not reading beforehand if it was needing to be built or not and assuming it just was)…… but I opened it and immediately gasped….. like it’s a lot to build! My poor brother in law just knew it was going to take me a while to build, even though I’m pretty mechanically inclined, so he thankfully took it and built it for me. It took at least 4 hours to put together, I’d figure even a little longer but there were definitely lots of walk away moments for a break. But that’s not where I got super bummed….. so it’s finally finish and my kid is losing their mind with excitement, and I’m not gonna lie, it looks super cool and it moved super cool….. for about an hour! That’s when one of the plastic pieces from the thumb broke and the mechanics part busts open and oil is now spilling out of it all over my kid and carpet. Then the middle finger takes a dump shortly thereafter! I tried to fix it, I got the middle finger working again but the thumb is just shot. So needless to say with all my rambling here, it went from super cool to not, to super cool again, to definitely not! I’m just bummed it took a long time to build for literally an hour of play and even more bummed that my kid wants me to build another one.
