What do I think of the LTDZ

  1. It is cheap: I bought it for little over 40 Pounds including shipping.
  2. It arrived in around two weeks.
  3. It is  small about the size of a pack of playing cards.
  4. The case looks actually quite good, it has a nice finishing and some labels. Also, there are a total of 4 LED's to signal IN/OUT ports operating, TG ON/OFF and general power ON.
  5. It uses a Micro USB connector
  6. No accessories were included,        except for the USB cable.
  7. Software required is a download from here
  8. A quick google will also find links to alternative software.

Performance:

For a 40 pound price tag please don't expect            performance at the same level as professional test equipment costing ten's of       thousands of pounds.

This unit does have some  limitations but is a useful       addition to the amateur shack.
