We've been selling the Hanna Groline range of measurement devices for a little while now and they seem to be top-quality when it comes to reliability and durability. Although we have had the odd return of this product, it's always came back as 'user error', and in particular, incorrect storage procedures - ALL pH pens/probes/sensors should be kept in the appropriate storage solution. Like with pretty much ANY brand of ph pen/meter/tester, treat them nicely and you should have something that provides both accuracy and reliability for grow after grow after grow.
