Make sure the container you test in has even amount of space around the probe as this may effect readings aswell.
I tested it in my refuge and it read 1.026 then in a cup it was 1.027 but when I used the silicone cup provided it tested 1.024. So for conclusion the meter works just don’t use rubbers provided!
Coral Vue should ship out free New testing containers to all the people that have already purchased one as you would think for the price you pay for accuracy how did this big screw up happen.

Lol, that's ridiculous! "Hey the cup we sold it to you with doesn't work properly"
Just noticed on J&L webpage it says "
Please note: It has been found that the included cup may distort the results. We recommend testing in a separate glass container (best), or a larger plastic container."
Would you still recommend one without use of the cup? Still thinking of getting one haha
