Solid. Been using it every day for a good month and has kept calibration the entire time. Durable enough as I may or may not have dropped it once or twice and someone left it in the green house cooking a couple times. Not me of course. Lol

I'm done with PH meters. This is just stupid. It's calibrated, it's re-calibrated and yet it will still tell me a reading from 4-7 when testing the same exact water. Recheck the meter with the solution and it's fine. I thought I wasStepping up my game like the YouTubers, this has just created a new nightmare. As I'm typing this review my PH is going over 8 while using PH down only. Is this some kind of bro science joke? I've been growing fire straight out the tap with 220ppm for over a year. For all I know with this stupid thing, I'm creating a bucket of acid.

Works perfectly for what I need it for.

Very easy to use and accurate. I tried a cheap one and it was a waste of time and money. I have been happy with everything I’ve purchased from AC Infinity.

I was sent a meter that was in a different case and white. It does not include the 10 PH calibration fluid so can't be calibrated.I love AC Infinity. Purchased a 3 x 3 tent kit from them ❤️👍Use to sell on ebay for many years. Descriptions have to be accurate. If it's A different color and can't be calibrated without additional purchase of $20 for PH 10 calibration fluid, . That's deceptive advertising

Great investment is the same as apera instruments
