### ⭐ Useless - wrong pin-out
*by M***L on 9 June 2015*

Completely pointless - they use non-standard (wrong) 9-way pin-out.

### ⭐⭐⭐⭐⭐ GOOD
*by B***S on 25 October 2018*

GOOD

### ⭐⭐ descrizione ingannevole, documentazione assente
*by V***O on 6 August 2015*

nella descrizione sembra essere un convertitore da 485 a 232 invece è semplicemente una morsettiera. Non c'e' nessuna documentazione assente
