Inspect the item for damage
Electrical items can experience wear and tear which can affect their ability operate properly. When purchasing second-hand, you will want to inspect the item properly - paying close attention to any damage. For games consoles, laptops, and televisions, look for any scratches or dents on the screen, as replacing this can cost you more in the long run.
Find out about warranties
Ask the seller if the warranty for the product has expired, or if it can be extended. This will provide you with peace of mind in case the product stops working or needs major repair work. Some electrical items - such as LED or HD TVs - might have short shelf life, so a warranty can be a useful document to have.
Inspect the item in person
For larger electricals, you might want to inspect the item in person. This will be your chance to check for any wear and tear and damage to the item before you make a purchase. If this is not possible, ask the seller for high resolution photos that shows any damage. You might be happy to order a product with a few imperfections, but if extensive repair work is needed, it could set you back.
Look into covers and cases for phones and tablets
If tablets have scratches or marks, you might still want to purchase the item second hand, and order a case or cover to conceal any damage. You will be able to find these online, but make sure you choose a cover that fits your brand or model. A comparison website is a good place to start, and you will be able to compare products using various criteria.
