I bought this for my seedlings. It works really well so far, I just got it today so I may come back later and edit this review. But for now it’s doing exactly what I need it to which is heating up my seeds to keep them humid & warm!

Wife bought these for when she starts her tomato plants in the early spring. Seems to work well. Doesn't have a heat control but she just puts a large towel between the heating pad and the plant tray and it works fine.Would recommend.

Don't try to use it in below room temperature. Maybe mine was faulty, but it overheated with cooler ambient temps. Be careful

This is perfect and easy to use. I’m using it to keep my sourdough starter warm in the colder nights.

Not sure if it is heating to its fully capabilities. The mat does feel warm and my seedlings have started to sprout. My expectation was that the mat itself would be warmer, but I could be mistaken. If I had to purchase over again, I would purchase a heating mat with a built in thermometer.

Seems to work as described, looking forward to starting my vegetable seeds for spring. I ordered 2 of these, they are the perfect size for my needs.They are usb cords which I didn’t realize, but likely I had the cubes to plug them into the outlet.so far they work great. Would def recommend these heating mats
