Magnusson Plastic Coving mitre box

I am a noob when it comes to DIY.
I bought it last week after attempting to cut the corners for my coving with another mitre and failing hopelessly. Unfortunately, I found that the angles I was cutting them wasn't good enough as well as the direction. In those aspects, I found this Magnussion mitre box very helpful.

Thing to consider:
- ensure your coving fits in properly with the box - the coving I chose was 100mm and it fits well in the box so it didn't move while i was making the cuts.

The only disadvantage:
- NO instruction manual as how to make the cut for the corners - I would have given 5 stars otherwise. I had to look at my previous mitre for these instructions.
