Frequently Asked Questions
What are the best kind of batteries to use in Fisher-Price® and Mattel® products?
A. We recommend using alkaline batteries with our products, as they are great for long-term use and help optimize performance. We don't recommend using Carbon-Zinc batteries. While Carbon-Zinc batteries may work well with low-power devices, they can drain after a short period of time and cause certain products to not function properly.
How do you assemble the rubber band in the Hot Wheels rubber band launchers?
On the underside of the launcher, each end of the rubber band should be wrapped around a peg on each side of the main launcher and then doubled up and hooked around the center tab of the moveable portion of the launcher.
Here is a picture of an assembled rubber band launcher!
