Bought this eyepeice today and it oozes quality I had to buy 2 as I use a binocular telescope so I am looking forward to giving them a try. I was getting varied reviews regarding Ultra flat field eyepieces and this one got really good reviews especially over the pond. I googled to see if there was a UK vendor for Svbony and I was lucky enough to find one and he had the eyepieces in stock so I drove over to Stoke to pick them up. They remind me of the William optics eyepeice but not with the high price at £83,99 I think I got a bargain because if they perform as well as they look then I will be quite happy.
