Honestly like I said, I highly doubt you will have any problems with it. Even if you do, it will be a while before they surface, or your fault
Your snorkel is supposed to made of LLDPE. The only source for "concern" compared to a safari snorkel is the plastic, that said LLDPE is some tough s***. I doubt ARB got a team of chemical engineers and spent years in a lab coming up with a polymer and additives for their snorkels.
Just google "LLDPE UV stability", cold weather resistance and UV stable are the biggest strengths of LLDPE. Also realize that in reality there aren't a lot of companies that manufacture raw plastic granules for molding. Everyone gets the granules from a few companies, melts them down and injects them into their molds. So there is usually very little variation in quality within a type of plastic. Safari may add additives to their snorkels to boost UV resistance, but one I don't necessarily think its needed from my research and two, its very easy to buy the additive and mix it in, cause guess what, very few people make that stuff too.
Last point, this is more my personal feeling and based solely on my perception. There are knockoffs for so many products these day coming out of china, yet the manufacturers don't say anything about it other than to warn customers, to make sure that what they buy is genuine since the knockoffs often use their logo to make it seem legit. They don't compare the quality of their real product to the knockoff, because there is no comparison. In this case, they aren't even copying the logo.
So you have to ask yourself, why does Safari go to such length to say their product is better?
Makes me think they don't have confidence in their product vs the knockoff
Last thing, put everything I just said aside, at $88 its more than worth the gamble. A snorkel is not something that can fail in a catastrophic manner, it'll just crack, like my rear bumper. In 6 months to a year we will know for sure if its good or not. Until then, who cares it looks (and sounds) cool and works perfectly
