Great entry level PH Meter.
Loving it so far. It holds calibration, and after comparing it to the reading of a $3000 meter, it is extremely accurate.

Super nice Meter w/critique
This product works as advertised and excels at it's job with one exception which is if you need to replace the sensor you can only buy it directly from the manufacturer because no one else sells it and in fact HM Digital doesn't even sell the replacement sensor at their own Amazon store.

Good Meter with multiple modes
This would be my second COM-300. This one came in defective, it would not take the calibration. It was throwing up errors. I have requested a replacement and expect it to be fine. I have used the first one for about 2 years and it works well.

NO BACKLIT SCREEN
This product is perfect and deserved of a 5 star review except one small oversight. There is no reason for an instrument of this caliber to not have a backlit screen. I'm not sure how I over looked this detail. Excels at everything as advertised. Worth the money and I will be keeping it until I find a suitable backlit replacement. Dang.

Junk
It has stopped working about three months after purchase. It always had problems where it would freeze and I would have to remove the batteries and reinstall them. No support response from the company.

Pretty cool
Works good, pretty hard to figure out at first but once you get the hang of it you’re fine

No included Mylar storage solution
Missing Mylar pack of storage solution. The package is open. Again, I just wonder is it used. Such incompetence
