I would have ordered more from Kaleidoscopes you', but since my two cataract surgeries, the focal length in both eyes are different, and I rarely can get even the more expensive one to be clear, with either glasses or no glasses. However, this one works perfectly for me more so in one eye than the other. I would highly recommend every thing on the site, but for my eyes, a lot of it is not in my focal range.
Pros:As I said above, everything, including quality and shipping and the personal note from the owner.
Cons:Absolute none. i have dealt with this company long before, and never had any complaints at all.
