Enjoy while you can!
As per other reviewer, the lack of lower frame meant one of the lenses was lost forever, when I rolled up but had some impact underwater from a bit of tree or whatever - this was within the first 20mins of wearing them... don't waste 30GBP like I did, and then have to spend a further 20GBP on a full-framed pair. Ps. I also think it's really rough that spare lenses aren't available... really unstainable approach.

Sorry, that doesn't work at all. When I first took off from the wakeboard, a glass was out and of course it went under immediately. The glasses do not have enough hold due to the half frame. Better to take full frame glasses. According to the dealer, there are no spare parts to buy. Thank you, 30 destroyed in 5 minutes.
