HOURS OF FUN
This great to learn about hydraulics and I consider it better than other items you have to assemble like legos, etc. because of the educational value. It is fully functional and provides hours of entertainment and although it was purchased for my grandson, I also am enjoying playing with it with my grandson. The instructions are very clear and the parts are well built, especially for the 'roughness' of a 10 year old assembling it. There is lots of value to this item and it is much more than a mere toy!

Fun and educational
Complicated build but oh so worth it. Quality is good and you actually learn something. This toy is an absolute blast, and my 10 year old loves it!

Grandson loved it
Purchased this for my 8 year old grandson who is great at building Legos . After purchasing this, I realized that it was probably too advanced for him, but with the help of his father, was able to build about 80% off this by himself. A lot of the work had to do with separating the little pieces before assembling. Once completed though, he loved operating the boxing robots with his brother. It is surprisingly sturdy.

Very happy with this purchase.
My son wanted robot boxers as a gift. We made a research and chose this set because it required preliminary self-assembly. We read the comments that it was nor easy for someone to assemble the set and decided that we should buy this set, because our son is not interested in simple toys. My son is 9 y.o . He did all completely on his own. To complete this set took him several days, and he found it a fun process. This is a really cool idea to give a child the opportunity to completely assemble a controlled toy. He had a problem with one little part, I wrote to the manufacturer’s support and the manufacturer quickly sent us a new part for free. Son has a robotic arm from the same company (also enjoyed it) He received it as a birthday present and completed it first. I absolutly recommend this set as an educational, interesting and well-designed game for 9+ y.o.

Must have for young builders too! Unbelievable value.
I purchased this kit for my 6yo son and I to work on, we have never done a modeling kit like this before and our prior experience is with legos. My son loves to build and he loves robots so I thought this kit would be a good transition to something other than legos. I knew going in it was going to take a long time and I set that expectation upfront. We would spend 30minutes to an hour once a week on it until we finished. I realized quickly I would have to do the cutting if I wanted the pieces to have clean cuts, I used an old pair of cuticle cutters that did just that, no sanding required (that’s what I had and worked for us) and my son did the building. He completed 80-90% of the build on his own and I provided guidance the other 10-20% and as recommended in the instructions, we recruited his 9yo sister to build the 2nd robot so we could finish faster. After the 1st building session my son asked everyday if we could work on the robot, he loved this project so much he couldn’t wait for me so he started to build and cut pieces on his own until he got stuck and he would ask for help. We love the side to side hip action, ability to change from upper cuts to jabs, interchangeable masks, kangaroo and robot. My son did ask if I could purchase additional masks for more variety of boxers, so maybe this could be considered as a future product add on. This kit is absolutely amazing and an astounding value at $35, we definitely recommend it to kids that love to build, the quality of the pieces, the experiment for hydraulic vs pneumatic power, and at the end of it all you have two water powered boxing robots that you built!! So cool!! This is the best toy I have bought in a while. I will look into purchasing more items like this, it is so much more than a toy. Thank you Thames and Kosmos.

Hace mucho tiempo mi hijo no tenía un juguete tan bueno, además de divertido para jugar, el armado es una muy buena experiencia. Hay que tener paciencia y seguir las instrucciones tal cual dice el folleto. Nos encantó!

Me encanta la calidad de sus materiales, es un juguete que ha disfrutado mucho mi hijo, además de que ha servido para que entienda como funciona un sistema hidráulico. El armado definitivamente requiere la ayuda de un adulto pero hasta esa parte se disfruta si se tiene el gusto y la paciencia. Tardamos aproximadamente 3 hrs en armarlo. Lo recomiendo mucho!
