LEGO Boost Creative Toolbox 17101 Fun Robot Building Set and Educational Coding Kit for Kids, Award-Winning STEM Learning Toy (847 Pieces)

I bought it for my 9 years old boy as a reward after he achieved good grade and positive comments from his teachers and school. He loves it so much. This isn't just a toy . It's an entire system that has genuinely ignited his interest in engineering and coding. So far he has done 2 models. Both are functioning well.

This is a must have lego product. I’m very staisfied. In compare to Anki robot, I suggest this one. It helps you to learn engineering.

Lego no deja de sorprender tanto a niños como adultos, y con este set no es la excepción. Un modelo con 847 piezas que incluyen sensores y una pieza inteligente que permite empezar con principios de robóticas desarrollando modelos simples o explorar con algunas ideas propias. Este set no incluye manuales impresos pues es necesario descargar una app que te ira guiando y abriendo mas posibilidades para el total disfrute de este set. Muy recomendable y sobretodo divertido!

Things started off quite well, with my 6 year old building the test robot with little assistance in about 45 mins. The test programming really began getting him interested in the kit. Will second another reviewer regarding documentation of the programming buttons, there isn't any. Lego, please send me that cheat sheet PDF as well. Then he started building Vernie. We did not have any of the app crashes so many people mentioned in their reviews, but then we're using the app on our basic Fire tablet, modified to use Google Play store apps. Midway through the build our tablet ran out of charge. Then started our struggle. After reloading the app, we slid through the instruction progress bar slider mistakenly until the end. At this point, the app assumes you've fully built Vernie and asks to connect. Vernie began talking, even though his feet and arms were incomplete. Not a very positive experience for a 6 year old. And there was no way we could go back to seeing the instructions again. There seems to be a "Reset Progress" button in settings, but we're afraid that will reset everything, including the test robot, test programming etc. Definitely don't want to go through all that again! Managed to search and find a PDF booklet of the instructions, but it has a ton of pages and not easy to skip several hundred pages to get to our page. Lego should've designed the app so that you could go a step back if needed. That said, I'd say Boost has definitely kept my 6 year old piqued and we're hoping to complete Vernie soon and will update this early review. Update (08/15/2017): We've finished Bernie (relying on the PDF instructions we unearthed via a Google search) and my 6-yr old is having a blast programming Vernie to do the various things he's capable of. Turning, talking and even responding to a handshake! I love how the programming language is just drag-and-drop. He's already learning the basic concepts of if-then and loops. I wish they included the programming cheat-sheet in the box, since icons on some of the programming blocks aren't at all obvious to an adult, let alone a kid. Upped my rating by another star purely for the programming being actually fun for a kid, and making a kid actually want to program more. Update (09/02/2017): Updating since there is a button that allows going back a step (as explained by Lego support in the comment), although it didn't work for some reason initially. I think you need to exit out of the building view and restart for the that button to work. But it did eventually and Lego support was good to point that out. Also, I'm running this on a Fire tablet which isn't officially supported by Lego, so I'll give them the benefit of doubt. Upping by another star, since there are very few flaws left at this point (biggest gripe is that pictures on some of the programming blocks aren't at all intuitive). So I'd like Lego to provide a cheat sheet of all the blocks used, either in the box or email it to customers. The bottom like is this is a fun kit which gives a lot for the money you spend and will help kids build logical thinking. What more could you want?

Great

Ordered a second BOOST set from Amazon as a “warehouse deal” advertised as damaged box. Unfortunately it was a previously opened box and the BOOST Hub was missing. Amazon provided a refund with no issues. I reordered a another BOOST set. This will be our second BOOST set. It is a great set and the kids have enjoyed it. Lots of options to build. Only downside is the requirement for a handheld device. Does not work with a laptop like the WeDo 2.0

This gift has entertained my grand daughter for hours. It has been a great joy for her.
