I have another Gravitrax set (desert theme) that my little one absolutely adores. This ocean themed one is just as excellent! The build quality is excellent and the adornments that come along allows him to customize everything just the way he wants. This is an excellent set that doesn't involve a tablet!

The GraviTrax Junior Starter Set – Ocean is absolutely adorable and so much fun! As soon as we opened the box, I was impressed by the quality of the pieces, they’re sturdy, well made, and thoughtfully designed for younger kids. I love that the set includes not just the building materials, but also sea plants and cute ocean creatures that really bring the whole theme to life.One of my favorite parts is the instruction manual. Not only does it include a range of fun and easy build ideas, but it also opens up into a cute little poster.Although my little one needed a bit of help at first, we had a blast building together. The pieces were easy to snap together, and the design makes it easy to switch things up and build something new each time. We’re already planning to get another set!

This set is really cute. I love the ocean theme. I do think it may be for kids on the younger side of seven like maybe 4 to 6 my almost 7-year-old and just turned eight year-old still had a lot of fun with it and the included instructions show you how to make different tracks, which is very nice & convenient, but my kids prefer to do their own thing and make their own tracks. It’s very easy to make your own track and it keeps keeps my kids entertained and engaged. It’s great for hand eye coordination, and problem-solving skills about physics and gravity, and how things work, which is great. I highly recommend this for Younger kids and I highly recommend trying the non-junior version of gravity tracks because that’s what I’m gonna try next for my kids and I think those look just as cool. The pieces included are very sturdy. I have no concerns about them breaking I have several other marble runs and the pieces are paper thin and if you step on them once they’re done so that is very, very nice Touch that they added because they knew the kids will be playing with these and kids are tough on toys it’s the little things . the little details that really really mean the most and Raven’s burger is top-tier in that department. This set can also be used to connect other grab tracks junior sets, which is really cool. The price is a little high, but for the better quality and a name brand that we trust in love I don’t mind at all.This would make a great Christmas birthday or Easter basket stuffer as well. It’s a great gift overall.

I have had plenty of Ravensburger puzzles over the years, I had no idea they made other products. As with the puzzles, this does not disappoint. Assembly is required and half the fun. Some just lay in place, some snap together. I was so happy when I discovered the second ball, a third actually would have been nice. The pieces are cute reminds me of sponge bob. The colors are a bit muted, I guess they are trying to depict ocean colors. I was certainly glad there were patterns to follow, poster cute. Once the grands get a hold of this, I am certain we will be discovering lots of interesting patterns. Great for imaginative play. Expansion packs are a plus. Sturdy box for storage.

Basically, this was everything I thought it would be, but better. It's pretty big––each tile is approximately 2.25 inches across. Additionally, everything is extremely high quality; if you're expecting it to be made out of flimsy plastic, you'll be pleasantly surprised!One of the fun perks is that it it also comes with an instruction manual that gives different tracks that you can set up (there are four different options)––so that way you can get some ideas before you start going off on your own. Personally, my daughter and I just wanted to do our own thing, so we skipped those. The flexibility here is great; you can keep assembling and reassembling. I found myself wondering what it would be like if someone got a few of these sets and added them together; they could make a huge run!If you're looking to have a fun activity to do with your child, even those who are a little older than 7 (I played with an 8 year old), this is what you're looking for. My daughter wanted me to mention that it's "so much fun!!!"
