I gave up on TrioTest after IPD took over. Last couple items I purchased from AppVision, they were helpful, responsive, cheaper and timely, so Im going to stick with them now.
PS: Also AppVision is a proper Siglent reseller, they also do MicSig gear and a few other brands of equipment.
PPS: Oops Tautech already linked reseller status from Siglent link.
