Is the SVBONY ultra wide eyepieces any good?

[Spacecake2]

I've been looking for a high power eyepiece 4mm-6mm (long eyerelief) 40$/24euro/30usd tops and saw these: SVBONY telescope Eyepiece FMC 1.25" 68 Degree Ultra Wide Angle 6mm 9mm 15m 20mm for Astronomical Telescope Monocular Eyepiece|angle|fmceyepiece 1.25 - AliExpress

I bought this set about a year ago and they seem to be good value for money. I am a short-sighted glasses wearer, with slight astigmatism, and they work with, or without, glasses.

They are identical to the "gold line" series of eyepieces which are well known and (re)sold by very many different sellers (normally quoted as 66 degree FOV). The only thing different is the colour of the line and the  barrel chromed rather than black. They are pretty good eyepieces, but suffer from 'kidney beaning' quite badly. I have the entire set (gold line) but very rarely use them - I prefer something less fussy about eye positioning.

I have the whole set and they are a very good value for their price.

The kidney beaning is an issue for the 6mm and 9mm and only on bright objects but the other two are fine. I quite like the 20mm, it is my go-to eyepiece when finding objects. Just used it on the full Moon last night.
