You get what you pay for--this is a 10-pack of 2.7x4" offcuts from PCB manufacturing, stacked without anything separating them, and put into a thin cardboard box that's scotch-taped shut.They're scratched, gouged occasionally along the edges, stained in places.Will they work? Sure, if your project is fairly simple and you have wide, not-too-complex traces, the surface scratches here and there probably won't affect your functioning. Without putting it under a microscope, none of the scratches look deep enough that they've broken through to the laminate.If you're making something incredibly complex with hair-thin traces and precisely-calculated resistance from component-to-component, well, you probably should spend a little more than 69 cents per board.This is keeping manufacturing waste out of the landfill and getting it to hobbyists that'll use it, so...as my wife said when she married me, "Meh, it'll do."

Boards arrived in perfect condition without any scratches , pits, or marks. So unlike other reviewers report, I can’t corroborate. They were slightly cut off square, but that’s not a problem since I square them up myself with a bandsaw. In general, I feel that they are a great value.

I bought these to etch for small circuit boards and for construction of handmade HO turnouts. They are cut to uniform size with square corners. The copper surface is securely bonded to the laminate and except for some minor surface scratches is solid. It cuts easily on a small table saw so I'll have a supply of ties for my turnouts in a short time at low cost.

I purchased the wrong boards. I needed double sided and bought single. This was my mistake and while waiting for the right ones to come in, I tested these boards. I cut traces in a finished PCB that is only 25mm in diameter on a Shapeoko 4 XXL. It's such a giant machine to see these boards on but the end result was amazing. As with any blank board, there is going to be the slightest thickness variation but I was able to cut across the entire board with no problems by slightly increasing my depth of cut to account for this and it worked great. I did not use standard PCB design software mainly because the board had to be so compact that it was difficult for me to get the design to fit. I ended up doing the actual design work in Carbide Create. I did not use board leveling so instead surfaced a base piece of MDF to hold the board and then did depth checks in all four corners. I would run the depth test until the bit cut the copper in all four corners and then run the cut at that depth. It worked perfectly. Now waiting for the right boards to get here so I can test my holders for the back side cut.
