SVBONY SV191 7.2-21.6mm Zoom Telescope Eyepiece

Very nice zoom. Mechanically speaking, it's solid as the Lunt 7-21, not flimsy like the Baader 8-24. From an optics point of view, it's pretty much the same quality as the other two, but at much lower cost. My only negative comment : it's not comfortable to use between 7.2 and 9.0 mm, you must position your eye at a very specific position otherwise you won't see anything. Other than that, it's a very nice zoom for both my H-Alpha and night-time telescope.
