We do not have a computer like that and we would not use it for anything else, so it does not really worth to buy one and ship it from the USA and then hoping to reproduce the issue and finally drop the computer in the garbage bin since we will not use it for anything.
But you could send us your system (PC) if you can live with lacking of it for a few weeks. If so then we can send you a DHL package collection, so DHL could pick the package up from you and deliver it to us.
Then you could tell us how exactly to reproduce the issue. (The steps to) and then we will reproduce it and debug the system. And if we can replicate the issue then we could fix it for sure.
And finally we would ship it back to you. (Maybe some gift too for your help)
Yes, sure, if the pendant is in original condition (not scratched and not abused physically) then we can refund you if you want to do that.
And it seems to me that not the pendant is suffering from the issue, but it is something in the software and certain installations which causing this problem, but we do not know what.
I'm saying this, because the same issue was reported by a few users with different pendants, the UCR201, the XHC HB04 too.
So, the problem does not seems to the UCR201 related. Maybe it is UCR201 plugin code, or somekind of timing issue, but again we don't know for sure because we cannot reproduce the issue at us and the number of users having this issue is low, so it is hard to get help from users. The situation would be different if more people would have this problem, then we could more easily find somebody who has enough IT knowledge to help us to debug the issue.
