Ajuste perfecto y muy bonita.

Good quality, 100% matches their 3020pro max v2

Fit perfectly, unlike the one I bought previously for the prover v1, which I didn’t have.

I'm really new to this stuff, I only bought the spoilboard because the YT tutorial I was following suggested it. The main thing I didn't realize is that you can't surface this entire board in one go using the 3018. I fully assumed you could, but my YT 'instructor' had a spoilboard <smaller> than his aluminum bed. This can get close, but you'll have to manually move it to get the edges. Further, I don't even know that surfacing it was required. If I could give my beginner-self advice; skip this until you need it for something specific. You'll save money on this and a special bit for it.Once I ditched this board and started just messing around I found that the T nuts were easier to get things attached to the bed anyway. Further, using the spoilboard's mounts with the additional height, I crashed my bit into them more than a few times - once actually starting to rip the nut out of the MDF.Long story short: if you know you need this, get it. It's a good value for what you get, I just happened to not need it yet (or maybe at all).

Before purchasing this spoil board, I read several reviews that said that it was not accurate. I was concerned but purchased it anyway. The alignment of the holes and T-Nuts leave little room for error. I can see why some said that it wasn't correct. Maybe it wasn't for them. When I first tried to align it, I thought they might be right. But for me, it was correct, but the tolerance is very small so you have to be patient to get it aligned correctly. After that was just fine.

Just what I wanted.

I extended the bed on my 3018 Prover v2 which caused m to order another spoil board and it fitted perfectly.

The board is not even close to being flat. Each hole where the tread inserts are placed is raised by at least 0.5 mm (1/32”). One could argue that the board is meant to be planed, but then, why are there markings on the surface? Planing the board would erase all that! For rough/crude jobs, this unevenness would not be a big deal, but for fine work (like I do), this board is not adequate. The low price is definitely a plus, though, and I used mine as a template to make a better one.
