Say a class of 20 students...one kit per student?** A: I wouldn't. The peices are strong when together but there are a handful of screws that need to keep their place. Once the screw threads "bite" into the plastic once, the strength of the attachment will lose alot of integrity if taken out and returned. Also, there are some adhesive pads that the "fingers" use for traction/purchase that won't peel off very well. I'm afraid that the pieces very likely would break if carefully taken apart and reassembled. I'd go as far as saying that it's likely that you would need to purchase 24 for a class of 20 to insure a surplus of "extra" parts for any that may break during assembly. Good one time assembly project though. Thank you for being a teacher. I hold teachers in the same regard as first responders as heroes. Bigs hugs for you. **Q: I am missing a P2 screw, this toy was a gift, how do I get a replacement?** A: I haven't had to contact their support line.........buut, the p2 size screw is pretty common.....if you have any old electronics collecting dust, you can probably salvage one from any old tech laying around. **Q: A P2 screw is missing, can you send one please?** A: We are also missing that screw. We're you able to find a replacement for it? ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect STEM Gift: Fun and Educational Mega Cyborg Hand Kit! *by on Reviewed in the United States January 3, 2025* I bought the Thames & Kosmos Mega Cyborg Hand STEM Experiment Kit as a Christmas gift for my 9-year-old son, and it was a huge hit! From the moment he opened it, he was excited to dive into the building process.The instructions were clear and easy for him to follow, and he managed to assemble it mostly on his own, with just a little guidance. Watching him figure out how each piece fit together and seeing his pride in completing it was priceless. The kit provides a fantastic hands-on learning experience, teaching mechanical concepts and the basics of hydraulics in a fun and engaging way.Once assembled, the cyborg hand is incredibly cool. It fits comfortably, works smoothly, and my son has been having a blast testing its capabilities, like picking up objects or pretending he's a robot. The fact that it’s adjustable for different hand sizes means he’ll be able to use it for a long time.This STEM kit is not only entertaining but also educational, sparking curiosity about engineering and science. I highly recommend it for any kid who loves to build, tinker, and explore how things work. It's a gift that keeps on giving! ### ⭐⭐⭐⭐⭐ Challenging but Fun Build! Perfect with Adult Help *by on Reviewed in the United States January 11, 2026* We bought the Mega Cyborg Hand for our 7 year old, and it has been such a fun and engaging project for our whole family. Building it together has been a great experience, though I would say a 7 year old definitely needs adult help and guidance for some of the steps. There are certain parts where an adult is required, but that actually made it a really enjoyable hands-on project to work on together.Our 10 year old also loves fiddling with it, which shows how well it spans multiple age ranges. The instructions are very clear and thoughtfully laid out, making the build feel much less intimidating. I especially loved that some pages in the manual include fun comic style stories and interesting facts about the physics behind how the mechanics work, it’s a great educational touch!We have absolutely loved this purchase for the value and are excited to finish building it and start using the hand. Highly recommend for families looking for a meaningful STEM project to do together. Age range: 7+ ### ⭐⭐⭐⭐⭐ Great, maybe age 9-10+ if you want them to do it independently *by on Reviewed in the United States May 9, 2026* This was awesome!! My kid needed something to keep himself busy this did the job. He’s 6 so did need more help but didn’t mind it. It turned out so great and could use it as a time to teach how hydraulics work. Great quality little large for his age but again. He’s younger than one might get it for. It is very complex and a little harder to screw the screws in but we loved the quality time. ## Frequently Bought Together - Thames & Kosmos Mega Cyborg Hand STEM Experiment Kit | Build Your Own GIANT Hydraulic Amazing Gripping Capabilities Adjustable for Different Sizes Learn Pneumatic Systems - Klutz Lego Gear Bots Science/STEM Activity Kit for 8-12 years - STEM 13-in-1 Education Solar Power Robots Toys for Boys Age 8-12, DIY Educational Toy Science Kits for Kids, Building Experiment Robotics Set Birthday Gifts for 8 9 10 11 12 Years Old Boys Girls Teens --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.sa/products/223966919-thames-and-kosmos-mega-cyborg-hand-stem-experiment-kit-build](https://www.desertcart.com.sa/products/223966919-thames-and-kosmos-mega-cyborg-hand-stem-experiment-kit-build) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-07-05*
