Penna starata e forse già usata
La scatola ha segni di usura, all'interno sul dispositivo c'erano dei PELI, cosa che mi fa pensare che sia già passata per le mani di qualcuno. Inoltre l'oggetto é totalmente starato, misurare diverse acque in bottiglia. La Levissima che dovrebbe avere 80Ppm ne segna 10. Vergognoso per il prezzo a cui viene venduta. Proverò a tararla e valuterò la restituzione non dovessi venirne a capo

Fast and accurate
Seems very well built superfast reading and very reliable. I’ve been using this one for about a year now with zero issues. It’s so much faster reading than the competitors that I’ve used.
