Review on PicassoTiles 3-In-1 Building Block Set: Rocket, Bus, Train Theme For STEM Learning And Early Education - Magnetic, Pretend Play Toy For Kids by Jason Rosekrans

I was super frustrated when first trying to put this together with my 4 year old son, because no matter what we did, the ferris wheel fell apart before we could finish building it. My son was sad that we couldn't get it to stay up, and I felt bad that I couldn't figure it for him out either. I wrote PicassoTiles customer service asking for some help and they were incredibly unhelpful and honestly a bit rude and condescending. They told me that they don't provide directions/instructions because they want to promote the child's creativity for building items. Sure, that's great, but we bought this set to make the ferris wheel shown on the front of the box! They sent me a youtube video of someone else building it and I tried several times to replicate what he did, but it kept falling apart.Finally, I stumbled upon the secret! You must have the hexagons pushed together as close as possible before putting any other magnatiles on. If they are farther apart, there is too much strain on the tiles and they fall apart. Additionally, we have found more success putting all the triangles and squares on one hexagon before building out the next hexagon, and THEN connecting them with the squares. (This is not how they did it in the video!) By doing both of these things, we were finally able to complete the ferris wheel. Still, though, a couple of hard spins by a toddler is all it takes for the whole thing to fall apart.It's also very irritating that the light-up squares need special batteries (that are not included), yet there's no mention of this on the box or in the description. These aren't the type of batteries that most people just have "on hand," and it's frustrating to toddlers to have to wait to use this special feature.
