It is great for trimming, but I could not justify the cost, so I used a 50% off coupon from JoAnns and bought the smaller one (not the really tiny ones) of Olfa and found a lazy susan for 90 cents at the thrift store--took the top off and cut a piece of plywood square and cut the matt and attached it to the top and the turner to the bottom. I just used lots of double stick taple. It works great for a fraction of the cost.
