Working well as advertised.
It’s all they said it would be.
Definitely worth the extra money to buy this over the other brands on the market. This is made of very heavy-duty material, is easily regulated with a heat controller (sold separately) but the thing that really sold me on this item was that you can daisy-chain multiple mats together and use one controller for all of them.
This mat is very weak - it's unable to heat pots or flats when in temps below 50 degrees F. Not for outdoor use must mean for somewhere other than a greenhouse, like the interior of a climate-controlled house. I bought this product to replace an older mat. Since I've had to bring my starts indoors each night, I'm putting my old mat back into service with my new digital thermostat (which works quite well).
