What to know before buying

Listing details to confirm

The stated 40-minute runtime is a manufacturer claim for both rechargeable packs after about two hours of charging. Customer feedback separately raises battery-life and reliability concerns. The controller requires AA batteries, and the listing says these are included, while its contents list does not mention them. Add only a small amount of clean water to the designated inlet. Adult assistance is recommended when filling it.

Customer feedback praises the dinosaur's appearance and suitability as a children's birthday gift, but also reports concerns about build quality and reliability, including reports of units stopping within two months. Battery life is mixed, with some feedback describing about five minutes of use. That is notably shorter than the manufacturer's claim of about 40 minutes using both rechargeable packs after about two hours of charging, so treat the stated runtime as a claim rather than an assured result.
