I don't doubt they are competent when they choose to be. My experience with sending them a 16 ga. Rem. M-31L for pre-paid restocking to custom LOP and drop specs with a modified off-the-shelf stock was a costly disaster that lasted many months -- similar to what canvasback describes and too unpleasant for me to want to wallow in the details again.
Edited to add a photo that doesn't begin to show all the problems with what they delivered and failed to deliver -- including never returning my original stock. I eventually got a refund, then had to pay much more than the original cost to have this stock re-made as near right in all dimensions as could be salvaged.
