Very pleased with its performance. Not excessively heavy like some wide angle oculars.
Ok, it is not a Nagler, but then you aren't paying for a Nagler. But what you are getting is a great eyepiece with a immersive FOV. I purchased mine last year at Oregon Star Party and it has definitely become my favorite eyepiece. I use it in my red tube Coulter 13.1 dob and have had great results. This year I'll add the 11mm to my collection.
