KB: This has now turned into a saga spanning a year and four faulty units. Bought the first meter in September 2022 which was bone dry and not working so returned. Got the second unit from a local authorized retailer, which worked for a few months and then would not calibrate. Took it back to the store and they gave me the third unit as a replacement, which worked for about 2-3 months but hindsight was faulty from the beginning as it would randomly reset, not turn on, or turn off. Took it back over the weekend and was given the fourth unit. Put some KCL solution and tried calibrating but the meter is stuck on 7.0 and doesn't even recognize the 4.0 solution. One poor unit - fine. Two - this is frustrating. FOUR bad units???

David: ¿Qué decir de Bluelab? Cuesta más que otras marcas baratas, pero a la larga te compensa por duración y calidad. Medidas muy precisas y buena construcción.

Tony: First let me say DO NOT be discouraged from the one star reviews. I can understand someone being upset if they buy a new pen and get one that’s broken but if that’s the case none of us would ever own anything. It is absolutely impossible to buy anything that doesn’t have a bad review because of something that in many cases that has absolutely nothing to do with how the product works, go look up anything you own and love and someone had an issue, seriously go look and see, I’ve tried it there is nothing I’ve found that everyone loves. This pen is awesome if you are a grower and ph is vital and you want to be a next level grower. I’ve had mine 2 years and when it stops working I will immediately get another one. It does take a small bit of little effort to add a few drops of storage solution that you have to buy extra but that last a long time and it’s worth it to me. You add it after each use to keep it hydrated. If it dries out the pen is not ruined like some say but you might have to recalibrate which is easy after your first few times, especially with the step by step YouTube videos available to watch while you’re doing it. Just remember there are a lot of lazy...

Mike Schmidt: Although I bought this pH meter for my wife for hydroponics, she decided to donate it to me for aquarium purposes - she's continuing to use a much cheaper unit for now. It is CRAZY that aquarists use chemical test strips or vial/drop test kits to measure pH rather than use one of these! Tropical fish stores should be selling these routinely!!! Unlike the cheap pH pen we used before, this one only displays to 1 decimal place - which makes sense. To get an accurate reading, it's definitely necessary to swirl around the pen gently for long enough to get a stabilized reading. The pen is fragile and must be handled with care. It needs calibration, which is a really easy process. It needs to be kept moist, which is also not difficult - especially if using it routinely. Definitely two thumbs up - we don't know of anything better.

Billy V.: Bought this about 18 months ago and I have never really trusted it just from the readings I get. Found out the other day from a youtuber I watch that his takes about 20 seconds to read and shows a check mark on it when it has the reading. Mine usually takes about 4 or 5 minutes and i didn't know it had a check mark. It has auto shut off and i can usually get the reading before it shuts off but sometimes i have to turn it on again and wait for it to stop reading. Bought a vivo sun pack of a ph meter and a separate ppm meter and they are fast and accurate ( as far as I can tell comparing it to the bluelab ) and vivosun is way cheaper. Wont buy bluelab again
