On one the gearbox had major work done to it and made it worse performing (Drained a 7.4v 1450mah lipo without firing a full high cap mags worth of bbs), noiser then before and made irreversible changes to the shell. I had to replace the entire gearbox.
The other sounded and performed fantastic, but was reassembled in a hurry to the point the trigger wouldn't reset in semi.
Both were longer then usual jobs and I was charged at a premium for.
Because it's a real pain to ship back and/or drop off I couldn't be arsed in pursuing it, sold one at a big loss that didn't recover even the cost of the repair work let alone the rifle and parts. I know that's my fault I didn't pursue the issue. These are things that could have been picked up on if tested for a reasonable amount of time before being sent back to the customer.
Going by conversations with other people in private, I am not the only person to be left a bit disappointed.
I think better decisions could have been made whilst the work was being done to reduce the cost and get things performing as they should have.
Either way, I have put it behind me now.
