Unless it has changed the 90 day warranty on refurbished products is honored by Nikon with the Sellers who market them.
About 15 years ago I picked up a refurbished Nikon 10x35 EII at High-Point Optics in Northern NJ for about 250.00. They had a box of about a ten of them that I could chose from. (Edit: It's name "High Point Scientific.")
I have used mine without any problems since I purchased it.
I've been reading good things about it. Compared to my 1st gen CL, the HG has much wider FOV, closer focus, faster focus and is about 1 ounce lighter. Should be a little sharper on distant subjects I would think from what I've read in reviews. Hoping I like it and it works well with my eyeglasses.
I hope it works for you with glasses as well! I'll be keen to read what you think of them, as well as Chuck and others. I have a definite soft spot for these bins. Went for lunch at a local park today, first day of spring here, pizza and beer on the grass and watched hundreds of Maguari Storks kettling and drifting over through my MHG 8x30s.
