Many people in this thread have gotten a defective ATU-10 from Chinese vendors on eBay/AliExpres/....? These have quality components but bad manufacturing (cold solder joints etc.). I too got one of these bum units from eBay.

BUT, here is the encouraging story: The seller hison-818 was absolutely great to work with. We went through and ruled out user errors, he understood my configuration in which I was testing the ATU-10 (Rig to ATU-10 to a known good Dummy load with plenty of power capacity). Within 1 day of triaging the problem, he dispatched a new ATU-10 after locally testing it in the same configuration. I received it yesterday (5 days later), worked perfectly. Last night i WSPR'ed on multiple bands with plenty of hearing k1jbd reports on WSPRnet. He did not ask for any additional charges, postage or even to return the old unit (which would be very expensive from US to china from a postage point of view).

Based on the above I can highly recommend hison-818, a honest vendor, who has excellent customer service and cares about the customer.

As someone mentioned, it sure looks like the kits are identical, at least for the most part.? So I have a feeling that 9 out of 10 sellers probably have no idea what they're selling - they buy in bulk and sell one at a time for a few dollars profit.? So identifying which seller is better than another is mostly impossible.? It comes down to how well they look after you after the sale, if you have a problem.? I learned this after my first ATU-100 purchase, which is still being dealt with several months after the fact.

I ended up buying a second unit from Hisonauto, who might be the same seller you mentioned.? This was after the first project I mentioned from a different seller exhibited odd behavior.? I exchanged a few messages with Hisonauto and decided that he has technical knowledge.? I wouldn't doubt he's also a ham.? His kit used axial Schottky diodes instead of surface mount and when I completed the assembly, it ACTUALLY WORKED!! ;-)? So I would agree that Hisonauto is probably a good bet when sorting through the many sellers on Aliexpress.? I would deal with him again.

I've ordered another unit from a different seller (after receiving two defective units from Hisonauto). I felt bad for him as i was refunded and did not have to return the failed units but that was the ruling from Aliexpress. I've got another one from a different seller which is currently in transit and may take some time to arrive due to Christmas delivery times. We shall see. 3rd time lucky hopefully.

Thank You all for your kind consideration, the ATU-10 is sold.
