## Customer Reviews

### ⭐⭐⭐⭐⭐ A great product, good value for good times
*by D***N on 1 March 2026*

my kid loves these expansion packs to gravitrax, and this was no dispointment either

### ⭐⭐⭐⭐ Expensive
*by S***E on 22 September 2024*

Found it expensive for what you get but lb loves it

### ⭐⭐⭐⭐⭐ The packaging's great, but the ideal set is not the best for me.
*by S***N on 3 January 2026*

This is a great addition to your track but only if you're choosing this over other viable options. The quality is great, but for me it's hard to fine-tune in my tracks. If you really want the trampoline, then go for it. But remember that this is hard to set up in tracks. However, the angled height tile is a must-have, because you can easily replicate the tiles from the 2025 advent calendar. But despite the ups and downs I have with this set, I'll still give it five stars because there was nothing wrong with any of the packaging and the product arrived to my door in only 2 days. Of course, take your hopes down if you're in Antarctica.
