A bit dubious concerning accuracy in the beginning
I seemed to have variations in my EC measurements in the beginning. I used a calibration fluid, which that or the Truncheon were suspect. . I contacted Bluelab twice, they answered promptly and they gave me some good advice. If you don't have the cleaning kit; which I don't, they advise plain old baking powder. Make a paste and give the electrodes a good cleaning . I used a piece of chamois on a plastic handle (non oily) They sold these to clean styus on analog record decks. I began to use the Truncheon with confidence. I have tested my tap water which comes out between EC .3 / .4 - Rain water doesn't conduct and shows nothing on the scale as it should. I am sure it is working fine now. The nutrient charts showing dilution and target EC values are in the 'ball park'. Initially one considers it expensive? however the guarantee period gives assurance and value. The Truncheon is very well made/manufactured so very durable and should last a long time. Conclussion: very good value and recommended

Ordered and received a faulty product, amazon sent a replacement the next day. Spoke with Bluelab directly as well they were very helpful. 10/10 tool, somewhat analogue, no need to worry or guess anymore!

product arrived in perfect condition. works great for my soil cannabis grow !! I like that it has PPM & EC so I can track both easily without having to do the mental conversion. And I like that its a big ass wand. makes me feel magical around my plants. Expensive but if you are trying to grow well and know what your doing - spend the $$

You get what you pay for. There are cheaper alternatives on the market but the peace of mind that comes with a market leading brand is priceless. Complete automated function with adjusted readings in all conductivity scales, no calibration required, tough bomb proof design. If you are looking at alternatives then I highly suggest to save your pennies if need be and purchase the very best from the very start, as my title says, "buy once, cry once" instead of continually wondering if the readings from a lesser meter are accurate and then purchasing another, another, and the a Bluelab.
