Ahoy, dropped in for a fill and picked up a set. 1st impression is that these are split glass lenses. The lower '1.75' dioptre focal is on a 10 degree angle to the top 3/4 of the lens. I thought at first this maybe a potential first place to chip.
After 3 dives over 40m they worked as advertised. Pro's: In stock and they will fit most faces - I have a mashed nose so 90% of low volume masks do not fit me - this does. Con's: I don't like the thin soft lower skirt. It could have been my fiddling at 38m with an unfamiliar mask but it is uncommonly soft. It might work well with the hair bearded ladies. :) They do the job well. Recommended for the weak of eyes who need that little boost to focus at the forearm.
