Bottom line: Works okay, but needs improvement
I have been a disc planner waaay before it was a trend and I wanted to like this punch. I have been on the hunt for a single disc/mushroom punch so that I can add custom chipboard, thin plastic/metal tip-ins/inserts to my disc notebooks and planners. I have the Levenger Circa, Office Depot Tul, Staples Arc, and Happy Planner punches, so I know what I am looking for in a disc/mushroom punch.
This punches through matboard and thin plastic, but the mushroom top is really not large enough to make thicker materials slide easily on the discs.
However, for thick materials like matboard or leather, if you have a single heavy duty 1/4" hole-punch that punches easily through chipboard/metal (e.g. crop-a-dile) you can use this to punch the initial holes and then use as a guide and punch out the mushroom section with the 1/4" punch.
Bottom line it works okay, but it needs improvement!
What I liked:
1. depth from edge is great!
2. it locks closed
3. the guide is accurate and works well with all of the brands above.
What I didn't like:
1. small "mushroom top". Needs larger mushroom top so thicker materials slide better on all brands of discs.
2. removable punch guide. It's annoying if I don't need to use it.
3. punch catcher is small. I have been using it with the punch catcher open if I need to punch several items.
