I have had good luck with the less expensive versions.
You get more pieces and they stay down... but more air bubbles, so you have to apply them carefully and work them as clear as possible.
Only bad experiences:
- some were so harsh they removed your skin if you brushed your knuckles on them
(the middle pic looks to have the same texture)
- some were heavy
- some were not really transparent
- some had the top layer come off the base
Plus, buying the original rewards the actual innovator, and sustain him to design new quality products.
Yep. if you're short on cash, just wax the nose.
Hexa works so well - in the scheme of the costs of a wetty, board, paddle etc. another $70 or so is no big deal.
I say go for it as often it's the same stuff with Chinese cheapo
but let us know after 
somebody has to go first
