I love my T5 apart from one thing. I like the fact with the T100 range that you don't need to use switches or dials to use the features. I nearly always get my T5 out of my bag and the dial had been left in position the last time (not too much of a problem as it has a power save feature) but I am cautious about what would happen if I tried to get a voltage reading whilst accidentally set on Ohms for example. And I am unsure if dirt etc can get in behind the dial and cause problems in the future. I still use an old T3 which has no dials etc, gets used daily and it is over 5 years old and still going strong.
The great feature with the T5 is the open jaw current reading option, this is great for fault finding etc.
I have toyed around with getting a T140 for months but still can't bring myself to part with the T5.
milwalkuie are doing something similar looking my only bug with T5 is the dial and throwing it in a bag one day n catching it with CK choppers ( keeeeeech) but crimped n heat shrink sorted that
