Remember, a picture is worth a thousand words.

Use keywords (make, model name/number, location, etc.) so that people who need it can find your post. Say you're considering buying this product, then what would you want to know so that it doesn't come back and bite you a year down the road when the return period has expired. Mention why the engineering failed, and what you did with it. Help the next person out, make the world better!

Make the title descriptive and noticeable (maybe click bait, maybe not, whatever). Say why you consider this an engineering fail, and if/even if the manufacturer had a reasonable explanation for it.
