Using this vape holder is super easy. First, find a suitable spot on your Subaru WRX or STi's vent. Then, simply attach the holder to the vent without any cutting or drilling. It fits right in. When it comes to maintenance, a gentle wipe with a clean cloth every now and then will keep it looking good. Just remember, the vape device and juice are not part of the package, so you'll need to get those separately. Also, since it's made of Hi - Temp PETG filament, it can handle normal temperature changes in your car, but avoid exposing it to extremely high heat sources.
