... granted, one assumes that legal liability and product testing would have ensured that the item works as advertised, right?
As for crashes- it says to put the phone in airplane mode and shut down all other background aps. I run my phone in similar modes and it has never crashed under those circumstances.
That is a fair question, but an unenlightened assumption. What is the legal exposure and obligation of this company? And what are they worth/insured for? Well, as for doing our due diligence, has anyone actually read the legal disclaimers on the product web site (bottom right corner)? That was the first thing I did, and while it didn't give me a shred of confidence, I don't know, maybe Sunto, Oceanic, ScubaPro, etc. are not so different. I see no evidence that any manufacturer is bound to their respective products performing. Sunto for example "does not warrant that the operation of the Product will be uninterrupted or error free". My experience with Oceanic is identical, and product repairs are entirely at the company's discretion - even if the company has listed specifications on their web site, as well as literature - that are
not supported in reality on their hardware. (I have first hand experience with this, but my guess is that I should not discuss that here) Yes, you can sue, but anyone who has had more than a passing interest or experience in Law (not the TV type) knows that litigation is rarely a useful solution in this area. Stated specs are largely sales tools, and do not often reflect real life experience. We have all read the iPhone specs, Apple says my phone should be at 60% to 70% this time of day, in fact it is at 17%. What do I do, sue Apple?
So as divers, the phrase Caveat Emptor must take on added meaning, as not only your money, but your life is in the balance and you need to carefully choose your equipment and suppliers. So who would chose a primary piece of diving equipment that needs to be charged (possibly) during your safety stop? And you may need to open the case on the water in order to do that? Oh, your wife unplugged your charger last night to use the hair drier? - your dive day is now formally shot to heck, but on the bright side you can now go to the market to do some shoe shopping! two words - Risk Management.
Sound like a great idea that could use some more work-shopping. Like that good comment made earlier, to add a battery pack to the unit.
