It works as it should.
Its been altered since my previous hm tds-3 meter bought 2010. Its only 1 tds different from my original unit and ,3 different on the temp C degrees readings. It does take longer now to get a temp reading, my old unit settles within 10-15 seconds, the new units needs about 1 minutes to settle. The new unit now gives F readings too, nice tough.
All in all it does as intended. I did try a cheaper Chinese unit but it was so inaccurate I decided to buy this unit.
