The reason Labjack products are better than any other DAQ devices is simple: the support is top-notch — both in terms of the feedback on the user forums whenever I have a problem and the software quality + documentation. I use both Labjack T4 and U3 for digital I/O control of neuroscientific research equipment, and interfacing with MATLAB is trivial. Looking forward to future products with faster command-response times...

We have nearly 100 telescopes protected from bad weather by LabJacks. Every dome, every observatory building has the roofs/shutters open when the weather is fine. When we have smoke, fog, dust, clouds, rain/snow, condensing moisture or when the sun is above the horizon the roofs/shutters close. If there is a failure...i.e., a shutter doesn't close properly we need onsite personnel to be alarmed no matter what the hour. LabJack collects the data and a computer in each building processes the data and controls the closures and alarms us if something isn't right. We count on LabJack to get it right 24 hours a day--365 days a year.

I needed an interface with analog and digital I/O that could connect to a laptop. The Labjack was easy to deploy. I have since used it for several things, a good item for the toolbox.
