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

Best bang for your dollars
Super product ! I just bought another one to replace my first one. I got 4 years out of the first one. It probably would've lasted longer but I get in a hurry and tend to really rough with my pens. I drop it in a bucket of water several times without any issues. I've even kicked it a few times (accidentally). Super accurate, durable, easy to use and calibrate. Highly recommend Bluelab.

Works well
Bluelab seems to make good quality products. My EC pen has worked well for over a year now. It has remained accurate.
