Rondi Jo Mills: Didn’t come factory calibrated and didn’t come with solution to calibrate it.luckily I had some anyway.for those of you that are new it’ll have a check mark.if your readings seem high test it in the solution.whether it’s the ph pen or conductivity pen.if that is on point then your reading is accurate.which means your soil or water is too high or low in nutrients.not the product.

Gonzo: I started with ordering the grower's toolbox at the very end of January -- it was delivered February 1st and the EC pen was dead before June 1st. I figured that it wasn't too serious, since sometimes these things happen and it should have a warranty. In the meantime, I decided I'd order a new EC pen since I have to make sure to feed my plants properly -- they're very picky. The new pen arrived within days and after thoroughly cleaning and rinsing, as instructed to before calibration, I attempted to calibrate the new EC pen. No dice. Tried cleaning and rinsing again -- nothing. I contacted Amazon and got a replacement sent (props to Dash for getting me taken care of quickly and painlessly), and tried to clean and calibrate the NEW EC pen...to absolutely no avail. Still getting "Er" code on the display.

So it seems that no matter what I do, Bluelab products are simply not worth the effort to try and use and DEFINITELY not worth the cost. It's a shame, really, because I feel like I remember their products actually working when I first started using them 3 years ago or so. I will be looking for a new manufacturer for my plant feed analysis products and highly recommend that...

Dazastar: Cheap $20 TDS meter does the same job. The ppm reading is off about ~10-20 ppm off on the cheap one. This is way overpriced for the job it does. Only good this is water proof.

Hunterheff: Pen is great, durable construction and I like that it is flat so it does not roll away on the counter top. Don't like how the back light goes out and I can't get it to turn back on and I don't care for how it needs the unit button pressed for 3 seconds each time you want to Select another measurement.

Sunrise Sublimations: These are the absolute best ppm measurement tools on the market hands down. Don't cheap out. You'll regret it only to have to buy more equipment in the future which will end up being the same cost as this. Definitely a necessary piece of growing equipment. Super easy to use and read. Blulab always knocks it out of the park.

Paul: The build quality is probably the best but who knows. I have owned 4 meters in my a year testing PPM in which the other 3 broke. The first 2 were in the $20 range (not waterproof) and the 3rd was $75. I just returned the 3rd one as it stopped shutting off and simply froze up. I already owned a Bluelabs PH meter I love and I cheaped out for some reason. Anyone who has been self-educating in hydroponics knows Bluelab is good and I vouch for that. The only thing it needs is a cap and strap. The other review here is old and inaccurate.
