"I have been a customer of ADInstruments since 2012. Their PowerLabs are extremely easy to use, but more importantly reliable in collecting data for my research. I use EMG to record responses from transcranial magnetic stimulation (TMS), and need a system that is able to both record following TMS, but also externally trigger the TMS device for various stimulation protocols. The adaptability of both PowerLab and LabChart allows me to do this without any fuss. I highly recommend using systems from ADInstruments for their simplicity and reliability."
