DO NOT BUY - WILL NOT HONOR WARRANTY
I bought this PH Meter in June 2024. I went for the more expensive one due to bad experiences with the cheaper ones. Immediately I noticed that the meter required almost daily calibration. I waited several days before jumping to conclusions. I purchased multiple buffer solutions at my own expense to test and verify results. All inconsistent. Finally I contacted HM support and sent them photos and videos of evidence that readings were faulty. They made me ship the meter back to them at my own expense. After 2 weeks they claimed that they calibrated and tested the device and it was working fine, they could find no issues, and they sent it back to me. As soon as I opened the box I tested again using buffers and the results are way off again! See pictures. Fresh from their factory calibration. I have tried every way to cooperate with them. I have even asked them to send me their own buffers if they are so adamant the device works fine. I have sent photos and videos of evidence. And yet the still refuse to acknowledge the device if faulty. If they had been a little more transparent and helpful this could have been easily resolved. But considering their stubborn refusal to accept the facts or provide their own, I must warn anyone from buying any HM products with a 1-Star rating. Aside from the cost of the meter, all the buffers have also drained my wallet. Terribly disappointed and frustrated.

Good Product but...
The first one I bought stopped working after 4 months. So I bought for the second time. And this time the product came without any buffer solution. And most noticeably, the battery was completely drained. It wouldn't turn ON. I changed the battery and it was working.
