Great for the price. Cuts 1.5" letter good, anything smaller or more detailed don't work well.

Here's my detailed review:
For the price point, this blades are sharp and they work great for general use BUT they are not very accurate with detailed/small cuts. I own a sign shop and i use a Roland Camm-1 Gr-540 cutter. It's very accurate and cuts very detailed and small designs with genuine Roland blades but they can be fairly pricy. So i gave these a try and I'm not disappointed but I'm not satisfied either. Then again, I have to keep the very low price point in mind. The cross test cut is about .25 tall. (See pictures) The left cross was cut with the 60° blue cap blade (the best one out of all three blades) and the right one is cut with a genuine Roland Blade. Big difference on the detail and this is due to the thickness of the blade shank that goes into the blade holder. The shank of the blade is slightly thinner than that of a genuine Roland blade. When putting this blades on the blade holder, they go in very smooth and if you move them inside the blade holder you can actually feel slight movement on the blade causing the blade to move as it cuts. This also causes for some corners of detailed designs to not be completely cut causing lifting when weeding the vinyl. The blue letters on the picture are 2" tall and you cannot see any difference between this blades and a genuine Roland blade. So if you're using it for general use and you're cutting designs or letter bigger than 1.5", you will be ok. Anything smaller or more detailed won't do. I'll still use these blades for bigger design/signage. They are great for the price.
Keep in mind: this is based on a Roland Camm1 GR-540 cutter using Oracal 651 vinyl and being used for professional use.
