Review on Tempo Communications Professional Telephone Display by Jacob Ferrarini

Solid brand. I like Tempo more than Fluke. More functions and still lasts forever. Loudspeaker and wired walkie-talkie function (useful especially in the case of bad mobile network or last line tests). We have yet to test phone lines, and we'll always find them here and there. Don't forget a long cord, nails, and a phone jack. A+ recommend pace.
