The Navien tankless water heater does not work, period. We are on our second replacement tankless water heater because Navien will not work with us to remove its product from our home. There is little to zero tech support, and Navien is not interested in customer service. Once the Navien product is purchased, the relationship with Navien ends. We have spent $$$$ on plumbers & shipping, not to mention hours of our own time trying to reconcile the problems with Navien. The company has also lied to us about delivery of replacement parts, of which there have been several. We've had to plead for assistance, however, tech support doesn't seem to understand its own product. Our purchase & installation of the Navien has been a nightmare - don't make the same mistake we did - it will cost big $$$$. Buy a different product, not Navien.

reviewing the product, not from this seller. It odd against the itworks company policy to sell on Amazon. There is no way to be sure these masks aren't expired and you won't get the best results from an excited product. To get the 4 pack for 59$ and directly from ItWorks global so you know you're begging a quality product. Visit

These are great for protecting the interior of a car. They really hold water well and protect the carpet from getting wet Recommend them for light interiors especially
