  • Pen works well

    By on

    The pen has been great so far but the packing the liquids come in could be better. Just be very careful when opening the liquid the package it comes in makes it very easy to spill.

  • Simply the best meter I’ve used in years

    By on

    Not only did I receive this item in quick time, but I was able to use it immediately and get fast reliable readings. Do follow the directions and put the fluid in the cap to keep the meter wet. It makes all the difference. Other meters don’t come with the balance fluid for the cap. Love this meter.
