Our Twilight Enflame was stepped on, scraped on, drowned by, abused by, and scrutinized by us. To know if our product is really waterproof, we submersed our device with the lid open, and left it to survive the night. Immediately after pulling it out, we tested every feature to find that everything worked just as smoothly and perfectly as before. We also stepped on, and jumped on it to perceive how durable it is! Besides a few scratches, nothing changed.
