Keep your gadgets away from extreme conditions like direct sunlight. It is important to note that exposing your gadgets to sunlight affects the battery life and this will probably make it to break down earlier than expected.
Except your gadgets are waterproof, make sure to keep them away from water. Even though it may be waterproof, you do not want to constantly expose it to water. Prolonged exposure will damage your gadget. Do not drink or eat near your gadget to avoid “had I known”.
Make sure to occasionally wipe down your gadget with a damp cloth (definitely not wet). Your gadgets are covered with more bacteria and dead skin than you can imagine. This as much important to your gadget as it is to your health.
Keep your gadgets out of reach of children and pets. Never underestimate how quickly your kid or pet can smash your gadget, or even soak them in water. Never leave them unsupervised with your electronics.
