You are obviously insensitive to the spherical aberration of the exit pupil (SAEP), though that isn't too difficult an issue to overcome if you sit and hold your head steady at the eyepiece.
But, bear in mind that many of the issues these eyepieces have will not be visible at the very low powers your scope yields with them.
Here in the US, they didn't sell well because they were priced higher than the equivalent Naglers. You would have to be completely free from all aberrations in popular scopes in order to succeed at doing that.
I used these in a dob with over 5x the focal length of your scope, and found them just OK. Edge of field astigmatism was higher than the Naglers and the SAEP was an issue with the 14mm and 10mm, though nowhere near the level of the old Meade Series 4000 UWAs from the '80s and '90s. Contrast was excellent. Had they priced them under the price of equivalent Naglers, I think they might have succeeded.
Vixen has had this problem with every series of eyepieces they've made in Japan. The cost of materials and labor simply makes them uncompetitive given their margin structure. It's why the lines they still have are from China.
The key here is that reviews are merely a sampling of one observer in one scope. Since the scope matters, it should always be taken into consideration when weighting a review for relevance.
One thing for sure: if you like them, don't sell them. You might regret it later.
