What makes me crazy

So you purchase a product from us and it looks like this:

Keep it for several months and then ask to return it for full credit.

You return this:

We refund your entire purchase price.

Is this reasonable?

Here is the thing about it. We want to provide great service and support. And we want to have fair prices. Is this possible if every customer failure is ‘our fault’ and we replace equipment that has obviously has been abused under warranty without asking any questions?

I don’t know what the solution is.
