Ravensburger - GraviTrax Power: Starter-Set XXL

I haven't put this back together in a few months but this was a lot of fun to build tracks. The quality it's pretty good and while it's kinda expensive, it's worth it if your into these kind of things( or your kids). As far as using it, it's easy to put it together. BUT it's not so easy making a design that works. Lol. But also that is part of the fun especially if your making multiple tracks for the marbles to go down. There are a lot of accessories to buy to make bigger and better tracks. And with 3d printers the options are endless. Lots of ppl have made custom pieces that are really fun to add on. You can teach your kids a lot about math and physics with this and have a lot of fun at the same time! I would highly recommend this if they like puzzle games. It does use 1-2 batteries in each one of the motorized pieces. I think I needed 8-10 batteries. The nice thing is they will auto shut off after 5 mins or so of no usage. The motorized pieces have different color lights that do different things based on the color. IE, one setting bypasses the trigger. I can't remember what the other 2 settings are but it's pretty easy to learn. If you're thinking about buying this, just do it.

Very much please to buy this product. My kids are liking so much and they are busy with this innovative game. Its great leaning game. I am so happy to see them playing with this innovative learning game rather than watching unuseful, content on TV or Tatablet.

I got this Gravitrax at an amazing discounted price. The item is better than I expected. The item went on sale again for $35.00 less. I contacted Best Buy customer service, and the difference was reimbursed. I own several sets but this one by far is the best. I would definitely buy from Best Buy in the future. Keep up the amazing work!

Bought it for my 8 yr old son who loves it. Shoot, we both enjoy it. Very satisfying to build and watch. Set is built with Lego type precision.

I don't know why Best Buy Shipping sucks. Last year, I had 2 empty boxes delievered missing contents. This year....I am thinking what could go wrong with Gravity Traxx, which happens to be Non refundable when opened,......Well....It had been opened and mangled and then re-taped together and then delivered. I am hoping all the pieces are there because this was supposed to a Christmas present for my son.
