Excellent product
Gives good heat, very good size for price. Bought it to germinate tropical seeds, and am using it with a thermostat to ensure seeds don't get cooked - you need a thermostat to use with heat mats, whereas with heating cables (those I've tried, anyway, but this is maybe because these were low wattage for length, have seen ones now with higher - sometimes nearly double - wattage for the same length) I find they barely make enough heat to need a thermostat, even when laid closer than the recommended distance apart. This heat mat seems well made, sturdy connection to cable and with a decent length of lead - about 1 m, although this is a guess, maybe a bit more. It easily reaches 25 C in the pots, which I have in propagators with moist clay balls underneath them, so is regularly switched off by thermostat when it reaches the required heat. Could doubtless get hotter, too, if thermostat was set higher. It's about the same for heat output as the other, smaller heat mat I have, which also gives good heat. You can fit quite a lot of propagators of standard size on this mat, about 5 standard size ones, plus the same number of half size ones, I would guess. Haven't got it fully covered yet, so not totally sure, but based on those I have on it so far, would guess it'll easily hold that many.
