This rotary stamp is easy to use and pairs well with chalk ink (my personal preference for stamp pads). The patterns are small and cute and are very detailed for their size. Since I use chalk-based inks I haven't noticed any amount of ink filling on the patterns resulting in loss of detail, but I can imagine a particularly juicy ink pad could fill in the small designs terribly.
The stamp's entire body itself may seem a tad bulky at first glance, especially if you are used to acrylic stamps, but it stores politely in a drawer or case and saves a bit of space in the long run compared to a wooden stamp block set.
The rotary requires a little bit of effort to turn; not so tight that it's impossible to turn, but also not so loose that you can accidentally cycle through three designs. The rotary is thin and plastic and has grooves (similar to plastic twist caps on bottles), so if you have weak hand strength or your skin is sensitive to friction/tearing (again, similar to plastic twist caps on bottles) you may find using it to be a bit painful.
I do have some difficulty lining up patterns to stamp across an entire page which I expected due to the nature of the stamp, so I'm not put-out by it. I feel that's a problem that will depend on your personal ability to line patterns up, as I have an unsteady stamping hand and poor awareness of where a pattern begins and ends if I cannot see it.
If being able to align the pattern easily is a priority for you, or you're concerned about the plastic rotary hurting your fingers, I would recommend picking up some clear stamp sets or wood block stamps from Wonder Pens instead. However, if these points are not a concern for you, the Shachihata stamp is a lovely investment.
