I bought this LifeSaver unit specifically for emergency use, in case a serious disruption to the water supply means that safe drinking water is no longer readily available.
For that reason, I cannot really say that owning it gives me “peace of mind”. In fact, there is a degree of continuing uncertainty because I have to leave the unit unused and rely on the manufacturer's claims that, if and when the emergency arises, it will perform exactly as intended.
Testing it now would require opening and commissioning it, which rather defeats the purpose of buying and storing a new unit specifically for an emergency.
In that respect, purchasing it feels rather like paying an insurance premium: I have spent a considerable amount of money in the hope that I will never need it, while also trusting that it will work properly if I do.
Bearing in mind the huge cost of this product, I would have liked LifeSaver to consider providing a manufacturer-approved way for purchasers to test their individual unit after purchase and then return it to a fully protected condition for long-term emergency storage. Ideally, this could include a test procedure and a suitable resealing or preservation kit supplied with the product.
That really would provide peace of mind. I would know that the particular unit sitting in my emergency supplies had actually been tested and was working correctly, while still being properly preserved and ready for the day when I might genuinely need it.
Until then, I cannot honestly review its performance because I hope I never have cause to use it.
