well, so far this heater is working properly,so I'm happy with this product,thanks very much,and just a foot note: before buying this product, I'd bought a frost plug heater, bought through amazon here, so, what ever the common brand is they sell here,anyway,it failed after 2 weeks, ,,,,, thought I'd done something wrong, so I bought another one - and it failed in 3 weeks! they don't look damaged, but they're open circuit, and no longer work, and, I had them on a timer as well, so, the heater pad on the pan is also on a timer, and although the block is not real hot, the pan is - when the timer is not on, and as of the 29th of January 2022, it is still working,I've no doubt If I left it on full time, it would head the engine block up more than it is currently through heat soak,
