If I've made an error then I apologize and I'll do my best to make it right. So please give me a chance to work with you to figure out what's going on and what the best solution is.
Most of the time I'm able to get the unit working without the expense and delay of having the buyer sending it back.
I would ask that you contact me first via the Contact Me link at the bottom of the page and let me have whatever diagnostic information is available. There's no point in your spending time on the phone to the manufacturer as they're not the party responsible for resolving the problem so you'll just end up repeating the dialog with me.
Unless it's immediately obvious what's happened, please try and be as specific as you can as that will save us both emails.
So just saying "it doesn't work" will simply generate a response from me asking you how you've tried to set up the item, are you using the correct manual, what it did or didn't do, any error messages, sounds, signals etc you observed, and what you've tried already to resolve the issue. It also helps me to have some understanding of your level of technical proficiency so I can tailor my response to your expertise level.
For the avoidance of doubt, I will not reimburse any expenditure that you make unless I have specifically agreed by email to do so.
Normally repairs to items are not economic and it's usually best for me to refund or replace any broken item rather than to pay someone to fix it. I mention this as some people falsely interpret 'money back guarantee' as a blank check with which to run around getting work done by third parties with no prior approval.
Unfortunately they end up being out of pocket at the end of the day, and I'd like to avoid that happening.
