Hi there. Your anwer is quite short. Of course tlyour statement could be true, but my second thought is: A Nest Protect is permanently connected to AC power. The 3 lithium cells have a lifespan of at least 5 years. Moreover, the NEST Protect designers would be quite stupid to sound a firewarning because of a battery-faillure, instead of a warning that says: ‘please replace batteries’. Go figure: there will be not even ONE test engineer that will let such a stupid design flaw unnoticed! I had this false alarm problem already in 2 unit (both version 1) only after 2 years of continuous operation. One of them has been sent back to Nest, and they were so nice to send me a replacement u it (version 2 !!) The second Nest Protect (verdion 1) failed 1 month ago. To test your ‘replace batteries’ solution, I wwill just put new lithium batteries in that second failed unit, and will for sure report back about the result. cheers robbert
Hi there, Metallic plates, or paint that contains metallic particles will block the WiFi radio signals in the iPhone. As much as you want to personalize your iPhone, I would recommend you'll refrain from any 'bling-bling' that obstruct the radiosignals (goes for BlueTooth, GSM and Wifi) Rgds Robbert
