We test each of the boards and the tester initials them before they are sent. That's all we promise. We do not have any intent of? swindling people by purposely sending them bad boards.?
This is what I can do.
At your cost, send me the non-working board. I will personally look at what is wrong. If i find, in my opinion that the board is fine or has been destroyed due to bad connections or improper supply, etc. I will not send a replacement or the board back either. On the other hand, if there is a genuine problem that we sent a defective board to you, I will personally refund the money regardless of what HF Signals does. This is quite distressing to have to deal with this. My postal address is good on .
