Check what you need on day one
Read the box contents, power source and care instructions.
Count the things you need to supply
A battery requirement does not mean a battery is included. For rechargeable products, check the device connector and whether the package supplies a cable, a wall adapter or both.
Look for the stop control
Read the button diagram for the exact product. Learn how to stop it before trying other settings. Choose a straightforward control layout if you want fewer steps.
Check care before opening
Read the care directions and return policy. An accessory that cannot be returned after opening may warrant a size or compatibility check before you remove the seal.
