You might want to run your ad through a spellchecker. Bellowing isn't a desirable feature in a phone, and neither is vibranting, no matter how gorgious it is.
Sparklingly witty sarcasm aside, my point is that some people will tend to avoid eBay ads that look like they were initially written in crayon. You'll stand a better chance of attracting buyers if it's gramatically correct and spelt properly.
