Experience with new Shuguang not Psvane WE845?

I have the Antique Sound Lab 1006(845) mono amps, and considering trying another pair of 845's instead of the Valve Art tubes. I've seen photos of a Shuguang "WE"845 tube that looks sorta like a United 845, and not at all like the Psvane WE845.
Anyone who's already bought/tried it?
Thank you,
Harvey
