I got it yes it was very good

apresentou problema com menos de dois meses. nao esta preciso e sem confiança

I usually use a different meter...but that one was not working (I had let it sit too long and I could not calibrate it) so I went looking for a good meter. I landed on this one as it was highly recommended, so I figured why not. So I began my grow Back in Sept with this dual pen and as you can see, it's been amazing throughout the entire grow. I am about a week out from harvest. When I say she works really well, I mean she works really well! You do kind of have to get used to calibrating it but after that it's a breeze. If you need a good pH pen and a TDS meter, I highly recommend you grab yourself one of these.
