I have now had this rotary cutter for over a year. Although I really like the design, how it feels in my hand and the sharpness of the blades, the cutter wobbles as I cut which can be really distracting.
There is a piece inside that is supposed to separate the blade from the cutter but it is warped, causing my cutter to wobble. I'm really disappointed because I don't know if it came this way or warp soon after I started using it but it makes cutting more difficult.
