We use it, I only have experience of the mobile side on android. It is **** compared to Cash, if there is more than about 10 lines of text in the call description you cant see the rest, there are no scroll up/down arrows. Calls can be deleted from the device by the engineer, if the office delete a call or transfer it to another engineer , the call stays on the original engineers pda which usually means that 2 engineers go to the job. You cannot read the history of previous calls.
