What do I think of the LTDZ
- It is cheap: I bought it for little over 40 Pounds including shipping.
- It arrived in around two weeks.
- It is small about the size of a pack of playing cards.
- 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.
- It uses a Micro USB connector
- No accessories were included, except for the USB cable.
- Software required is a download from here
- A quick google will also find links to alternative software.
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.
