Pretty Cool
This is the first Lego kit I bought that didn't come with paper instructions. Instead I used the Mindstorms app to build and program the robots. Pretty interesting. So far I only built the buggy and that was fun putting it together. I wish the kit came with a play mat with lines for line following. The kit comes with 4 motors and 2 sensors. I hope that Lego will make It were I can buy sensors separately like they did with older kits. I haven't test to see if using the python programing can make the robot kit connect to a Raspberry pi, but that works it would be cool.

Expensive but worth it if you can afford it.
I hate putting a price on education, but that's the world we live in currently. That being said, I did feel like I got a ton of parts in this set, which is a rare feeling with Legos for me. This is a great intro into robotics young and old. Lots of unique pieces, precise motors and lots of room to customize, as you should expect with Legos. If I had to say anything bad about this, outside its price, I feel like the hub only being 6 ports is lame. Pop a Raz Pi into these boxes or an Arduino Mega for a fraction of the price. Curious if anyone sells break out connectors for all these sensors and motors. 6 ports is enough for learning though, I'll give them that. If the set was cheaper I would like to get 2 of these and have a build off competition to teach coding in a fun way.

Despite what some say, it’s worth it.
After reading some reviews on this set I was hesitant to purchase it. I owned the EV3 set once upon a time and everyone was acting like this is a downgrade from that one. Well after watching some comparison videos I decided to go for it and now I’m glad I did. While there are slight differences between this one and the EV3, I think this one is better. All I’ve noticed are improvements, especially considering how much smaller the intelligent brick and motors are. I also love how it has Bluetooth and it can be programmed on my computer or phone. Right out of the box I was able to build a robot that can solve a Rubik’s cube, thanks to instructions on the internet. I’m super excited to build more robots with this set. So far it has been a blast!

Expensive gift but worth it!
My teenage son wanted this and only this for his birthday. We couldn’t find it anywhere local so we ordered it through Amazon. I usually don’t like to order expensive items on Amazon and risk it getting stolen, lost or the box gets torn up. I took this chance since we couldn’t find one and it arrived in perfect condition. The way Amazon boxed it was incredible. The Lego box was packed inside a very hard, sturdy box and then boxed again inside an Amazon box with cushion. So it was perfect when we gifted it to my son for his birthday. He loves coding and making the robot pick things up and just being very creative with it. Our dog hates it when it moves.

Exactly what you expect
Generally speaking, a nice upgrade to the Mindstorms EV3 version. Best thing about this is that if you need technical support, Lego phone support is absolutely top notch. I found them to be extremely responsive, and they were very quick to replace defective or missing parts. If you're looking for a good storage solution to organize all the components, the Plano Molding 1363 Stow N Go Toolbox is just about perfect.

Great for STEM learning
This MINDSTORM Robot kit really brings the fun of building a LEGO kit together with learning basic programming structure. After building one of the designs, my daughter will then go through the process of programming it. The included programs are a great introduction to coding and there is enough left to the imagination for her to see what else she can program. Anyone who is a fan of LEGO should give this one a try.

It has quality Lego pieces but
The programming is limited

Engaging
My son gives it a five-star rating. It keeps him engaged and provides opportunities to experience coding in a playful atmosphere. He'll be nine years old in October, and he completes EVERYTHING independently. However, he has had some experience coding via the app CodeSpark. Lego Mindstorms is pricy, but he enjoys the activities, and it's where the future is headed.

El mejor!!!
El mejor kit de robotica que ha lanzado lego, a mi hija le encantó, viene con 5 modelos por defecto pero contiene actividades extras como el modelo pet gelo de la comunidad de fans de lego, ademas de muchos modelos que puedes encontrar en internet.

Where was this when I was growing up?!?
Bought this with my 8 year old son. Seems like an expensive piece of kit but the level of ingenuity and technology that this kit holds is absolutely priceless. Gives him the ability to build all sorts of different robots and then PROGRAM THEM TO DO STUFF!!! Like, seriously!?! This is college level programming for kids! Unreal how they’ve made this product and made it so easy to use for young kids! Can’t say enough about it. Mind blown. Hours and hours of fun so far with no end in sight. Want his friends to get the kit too so they can do battle:P

If you love your children and can afford this, buy it
So great for your child's development. Gets them thinking creatively and spatially while subtly introducing coding. Doesn't matter if your child has zero interest in technology, this is a must if you can afford it. The world is changing and basic exposure to this at a young age is beyond critical. While advertised for older children, my 5 year old thoroughly enjoys it with a little help every now and then which is great for bonding. Do you remember building a model car with your dad?
