Works perfect, great service!


WOW, super fast handling and shipping. Device looks and performs great! Thanks.



I have had the earlier version (ph2) of the pre-heater unit in my car for one year now and its working great! And now I bought this unit to control the heat for my cabin. Has been working superb the two weeks I owned it. Great product, thanks!


Superior quality at a bargain price! Tried a couple of other brands and this is by far the most responsive, reliable and well documented one.


Very fast, great communication!
