    • Great value.
Size: 4 Pcs Matte Black Style: 400mm
Exactly as advertised. Only complaint is that they were covered on shavings from being cut to size. Had to be careful not to get very sharp aluminum savings everywhere, but for the price thats hardly much of an issue.

    • Dimensionally accurate and well packaged
Size: 4 Pcs Matte Black Style: 350mm
Dimensionally accurate, packed well and no damage, took an extra day beyond promised and a bit pricey for what you get, but the best deal I found so happy with it!

The dimensions are wrong. While they are V-slots, and 20mm, the inner hole is 5mm, not 4.2mm, meaning you cannot tap the ends for M5. This is not what I wanted and not matching the description/images.
