I've backed the NDLR and MRCC, and I'm quite happy that you propose now an upgrade Kit for the NDLR. Your products follow up is outstanding which is rare ... and you prove it one more time. Thank you. Would it be possible that you provide the power switch also in your parcel, and the metrics where the hole should be ? Free to the customer to solder the power switch (or not) and create the hole (at the right place with the right diameter). Thank you again !
