There's no silver bullet, but some pointers... - do they actually suck? You're making sales after all. Call up a customer, and ask them to be honest. it could be you are fine and need to give yourself a pep talk. - bad demos tend to focus on the product and not the customer. By the time you are demoing you should know what issue the customer has. Does your demo start run and end with the customer's issue, with the cool features being pointed out as essential elements in solving it, or are they just features that you feel you have to show? One makes for a better demo than the other.
