How to Void Your Warranty - 
Do not upgrade any part of your toy gel blaster or pre-built gearbox as this will void the warranty. Upgrades refer to pulling any of the pre-built garbox/ or gel blaster apart or opening it up, painting the item, changing springs or upgrading the battery from 7.4v to an 11.v battery.

Charging Batteries

With the batteries, we recommend charging them between 1-4 hours.
When they are charging the light/s will flash and once it is fully charged, the light/s will turn a solid red or green.
Also once you start to hear the battery getting flat, please recharge it as running it flat can damage the cells.

Growing Gels

With the gels, they need to be soaked fully submerged in warm water from the tap for a minimum of 4-6 hours.

Once they have fully grown you can leave them in the water and keep them in or out of the refrigerator.

When you are ready to use them just drain of any excess water with a strainer before you feed them into the mag but do not dry them as they need to be lubricated to work properly.
