Negative
- A common ground / shield which is not connected. (Ie all angeschlossenene devices share permanently the ground line / shielding
- Housing Although stable metal, but not a nice surface: small bumps on housing (probably paint) offset and rotary switches, scale not concentrically around knob, but easy. These disadvantages, however minimal and the price OK.
Delivery of inkwell:
- Many fingerprints on device, presumably returns.
- Blister was not very clean and not sealed.
Summary: For the price very OK, so 3 stars
