So I received my square yesterday, sadly haven't had time to test it yet. But got here in The Netherlands in a little over a week in great shape. Too bad I had to pay € 41,- for customs and import fees, but sadly that is to be expected over here in The Netherlands.
Hope to be able to test it real soon!
But I was thinking, has anyone tried it yet with their Seneca (or other) parallel guide(s)? I think you would only need to use one and let the TSO square make everything square?
