W.O. 4mm Uwan

Anybody tried out one of these yet? I'm looking for a new eye piece and right now the the leading contenders are the Radian 3mm, Radian 5mm and the W.O. 4mm. My scopes are a 66.. W.O. pez, a 10 inch F4.6 dob and an 8 inch Celestron SCT, with the 66mm W.O. being the most used scope at the moment. I found plenty of reviwes on the Radians, but came up short on the W.O. 4mm.
Opinions anyone?

Thanks
Roger

Roger,

I purchased a 4mm UWAN for lunar/planetary use with my 80mm Megrez APO. It provides very nice views with no kidney-bean blackouts. Edge performance is almost as good as my 5mm Pentax XW, and it provides a little more magnification while being smaller and lighter than the Pentax. I plan to keep mine and can recommend it.
