I have had mine for about 8mos. now. Overall, I've been very pleased with it. Among its best features:
*User set conservatism- it can be set form very conservative to fairly liberal
*Having Trimix capabilities- I am not Trimix trained, yet, so haven't used that feature, but there when I am ready to use it.
*Multiple gas switching capabilities
*Wireless Transmitter- I use the transmitter only on my recreational configuration
*User set alarms
*An excellent download & planning program
*Reasonably priced for its capabilities
The only naegative thing I have to say about this, is it can be a bit complicated figuring out how to move from screen to screen on the computer & I must occaisioanlly review the manual to remember how to do gas switches or to change some of the settings
