Cap holding probe solution was smashed when it arrived. All the solution had leaked out and the probe was dry package was not damaged.

I let my old one dry out by mistake. I got this one so if I decide to go from hydro to soil it will still work. FOLLOW DIRECTIONS if you do the soil. KEEP THE PRESERVATION TUBE. This is vital. Cap it off and save it for when not needed. Other than that it calibrated quickly and fit my device.

I had my pen in water to keep it wet, and I pulled it out one day, to recalibrate it and the tip was totally gone.

Great product. Shipping was fast, product works as described.

Works great dead on before calibration. works way faster than other probes. just be gentle with it and don't forget to pre dig the hole before inserting probe in soil.
