Review: Nice addition - Purchased the main set for my 8 year old son who loves building and constructions toys. He thought it was the coolest thing ever. Lots of different pieces and plenty of pre-designed tracks to set-up. Great product! We also got the expansions. The loop was neat, if you position it after the magnet launcher it shoots around really fast.

Gravitrax is a great toy - hours of play

### ⭐⭐⭐⭐⭐ Needs ball speed, looping happens quickly
*by D***N on October 13, 2021*

I like this loop accessory but it needs a lot of speed for the marble to properly execute the loop. With that speed, things happen quickly so the marble is in and out of the loop almost too quickly to see, and the marble is fairly well hidden as it traverses the loop. I like the loop addition and I’d still buy it but if ranking additions for for visual impact I’d buy other additions first. On the plus side, there’s nothing to reset and once installed it works reliably and consistently.
