I cannot speak highly enough of them.
My set was initially LV - 2.5, 4, 5, 7, 9, 15, 20 and 25. All were obtained second hand from various sources at an average price of $77. They are crisp, clear, sharp to the edge and with 20 mm eye relief, are extremely easy to use over extended observing sessions. The other strength is consistency of performance across the range of eyepiece focal lengths.
I have since bought pairs of NLV - 9, 12, 20 and 40 for use with a binoviewer and singularly when appropriate. I have sold the LV 9, 15, 20 and 25 as they were redundant.
The NLV's are the same optics and so the same comments above apply. Buying new, I feel they are extremely good value for money. I was originally sceptical of the screw up eye cup mechanism on the NLV's but have come to appreciate them and I now prefer viewing through them over the older fixed flexible rubber cap on the LV's. The variable height eye cups on the NLV's provide flexibility for eye positions and the larger diameter cups (over the narrower LV cups) are more comfortable at the eye.
Yes the APOV is 50 degrees except for those 7mm and below at 45 degrees and the outstanding 40 mm at 42 degrees. However, I have almost never found this a limiting factor. The reality is that the vast majority of targets, celestial and deep sky can be viewed with the TFOV provided by these eyepieces in most scopes. If wide field viewing with the immersive effect of a large AFOV then certainly one would need to look for other eyepieces.
Cheers
Steve.
