I bought a sdm3065x three months ago, but still havent used it in anger. It came in and despite having a Siglent cert saying calibration checked in may this year it was out of spec. I have bought a few pieces of Siglent gear over the years with no issues, but I guess my expectations for a 6.5digit multimeter not being delivered out of spec made this experience a little disappointing.
In any case its currently still at Siglent, Im assuming getting a re-cal but they have had it 6weeks and got a promise last week it would be shipped back this coming week. I did buy it from overseas because the Australian distributor promised delivery twice and didnt deliver, so they had my money for 5weeks and then gave me a story it world be another three weeks, so I cancelled and purchased overseas and got it in a week only to get one thats out of spec. Another reason this has all been disappointing, not currently happy with Siglent.
Sorry for a downer of a post, guess I just needed a little vent.
