    • Great value !
Style: Grower's Toolbox
Buying these separately cost about $40-60 more. I found the initial calibration to be very easy ( don’t forget to soak the PH pen in the storage solution prior to calibration!!) and accurate. These two meters will be used regularly and I have confidence in their readings. I recommend do to the price point and value. Low price, high quality, fast readings ... show more

    • Super easy to use and calibrate
Style: Grower's Toolbox
I started using the cheap ph and EC pens, and the worked okay, but I was having regular issues, and the calibration was very convoluted. In contrast, these BlueLab pens are awesome! The initial calibration was a breeze, and they have needed very little to no care other than keeping them clean. My only quibble is that the backlight on the pens times out a little on the quick side. Not a big issue, but it would be nice if there was a light button so the backlight could be turned back on. My advice to anyone getting into hydroponics or just in need of a ph and EC meeter, gust get BlueLab. Anything else is a waste of money, time, and ultimately frustration. ... show more

    • Customer Support Saves the Day!
Style: Grower's Toolbox
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 anyone reading this review does the same! Edit: I managed to get in touch with customer service and they were not happy to hear about my dissatisfaction. The representative went out of her way to set me up with new solutions to calibrate pH and EC. Sent express directly to me from the manufacturer instead of an Amazon warehouse, so they actually worked. She also called me to follow up a few days later and asked if the solutions worked or if they needed to send a new pen. The level of dedication totally changed my mind about bluelab. ... show more

    • Lasted less than 2 months
Style: Grower's Toolbox
For the first 6weeks, it worked like a charm. I would measure it in the 7.0 and 4.0 solution and it was always on point. I followed instructions on cleaning, wiping dry before measuring and calibrating. Well just the other day, it would not work properly at all. Even after calibrating in the 7.0 solution, it would not give me a 7.0 reading nor would it give me a 4.0 reading after calibrating in the 4.0 solution. I would test it back and forth multiple times and it just wouldn't settle or read it right. At first I though maybe I had contaminated the solution, but luckily I have a 2nd meter and when I tested that backup meter, everything looked good on that meter. For the price, I would have expected this to last about 6months before it bellied up. ... show more

    • Bluelab PENGTB works!!!!
Style: Grower's Toolbox
We ordered this for our aquariums (we have 300). Upkeep on this item is simple, easy, and really nice to use. Everything about our purchase has been smooth, with quick shipping, and easy set-up. The calibration process is straightforward and the item is spot on with measurements. I think everyone that is into fish or aquaculture of any type should invest in these. They work, just like the should. We are very pleased to have this in our lives. ... show more

    • Terrible packaging
Style: Grower's Toolbox
I've only used the unit once so far, but I will say that I was disappointed in the packaging. The box isn't sealed and when it arrived (in a bubble-wrap mailer) the contents were all out of the box, including the two pen testers. You get enough calibration solution for the initial calibration and that's it, so be prepared to purchase more calibration solution. The KCL storage solution is also enough for one use, so be prepared to purchase more of that. In fact, that's what's preventing me from using the unit. I used the KCL solution to hydrate the pH pen and store it after the first use, then I threw the solution out. Now I don't have any to store it after another use until I receive the bottle of solution I ordered separately. Bluelab should make a kit (better sealed!) with a couple of 100ml bottles of all the solutions rather than one each of the single-use packets. ... show more
