    Gerador de manivela
    Brinquedo didático muito engraçado. Não vinha montado (como dizia na página do produto), mas é muito fácil de montar.
    Fiz a montagem conforme as instruções anexas, e deparei-me com um problema: a correia que faz andar o motor ficava com demasiada tensão dificultando o movimento. Optei então por colocar o motor noutra posição conforme se pode ver nas fotos.
    Só quando vim escrever este comentário é que verifiquei que o aspecto da montagem que se vê na imagem não é igual ao que vem nas instruções. Para além disso falta uma correia.
    Mas isto não é um problema. O gerador funciona muito bem tal como o montei, e vai ficar melhor quando eu fizer a alteração. A velocidade de rotação do motor vai ser maior, gerando por isso mais energia.
    Recomendo este produto.

    These are Great for teaching young children are older children or anybody even about electricity about energy, there are multiple short projects for the kids to do with this, quality product, keep the box and teach the kids to be careful with the pieces if they drop or crash against each other they can stop working, either way is fine though, but if you end up really liking the thing your wishes but the larger set that there's a picture of in the back of the booklet included

    This is a great science kit for young kids, and it is important for me to instill this in my kids from a young age, this is a great kit to get started, it is for very young kids - preschoolers and kindergartners - but my older children did it and enjoyed it too, it's a great way to introduce them to science, you can then reuse some of the equipment for other experiments such as the hand magnifier, I was very happy with the quality

    Most kids from what I've seen simply follow the instructions instead of going beyond them and utilizing their creativity, it fails as a truly educational product, my own kids and their friends played with them for a while and then moved on to other things, the product is okay, I think this is a decent educational toy, as long as you keep in mind that your child is unlikely to treat this as anything more than a toy

    Bought this set as a gift for my seven year old grandson, it is well thought through and designed for being safely handled by younger kids while still providing an educational introduction to the mystic world of electricity, I was astonished how after a little while this little guy was able to predict the outcome of many experiments before connecting to the batteries

    We got the super set for Christmas and after building a couple different runs, amazing !!! This set is awesome, plus other pieces I have never seen with my original marble machine, older kids and myself have fun building new tracks and runs

    I have a rule that my son has to get at least one educational toy for Christmas each year, it has been a great way for him to see things up close and personal, it is easy to view things with the dual lens which is wonderful for young kids

    A reallllyyyy great toy for a really young one, the bigger kids got some electronic things and I thought he'd be a bit jealous, but turns out the novelty of changing one's own voice was plenty satisfaction

    We got this for our four-year old's birthday, I think it would also be suitable for older kids who would require less help, overall educational and fun, just a fun activity but not a long-term toy

    I worried about it being `` too educational'' to be fun, but what a COOL TOY this is, a little like school, I can see slightly older kids doing this together, addictive and fun, wish this set was bigger !!!
