I bought 2 just before Christmas of 2022. They came very quickly. Two months later only one continues to work.I used one in the traditional way - laying (mostly) flat on a table with seeded cups atop in plastic totes. It has remained in its original location this whole time. That one is still working.The other one (dead one) was moved several times daily. I WAS careful with it, removing it gently from the lids of totes and keeping it (both of them, actually) relatively dry and kept it in a wide, loose roll. I thought this wouldn't be a problem since it was delivered in a roll, but I may have been wrong.I used plastic totes with the mats for bottom and top heat at night, removing the top mat in the mornings. I'm blaming the constant moving for the failure, but not absolutely sure about that. The thermostat still works for both mats, which is helpful.All of the mechanisms - wires/thermostats/plugs - are kept in their own dry tote. I had to bunch some rags beneath the bottom mat so the bottoms of the totes would make full contact with the mat - that mattered. And while I live in the deep South, there were many very cold nights. With both these mats going, it was warmer in the totes than in the house on some of these nights, so it was a good alternative for me since I have no greenhouse (I do cover the entire set up with thick plastic and blankets at night and remove them in the mornings).I suspect that these plants will do even better than those from a greenhouse since they will automatically be hardened off.The peppers show heat damage, but that was my fault as I had forgotten to remove the lids of the totes on a particularly warm and sunny winter day. But there are happy leaves coming above them and it won't be a problem.I'm ordering another brand to replace the mat that died and will compare and contrast as I go, since I'm hoping to increase my numbers next year.Overall I am very pleased with the one, and very disappointed with the other, yet grateful that it worked long enough to get me past the bulk of the cold weather. In the future, I will have to come up with a way to move and store the top mat during the day in a way that is even more gentle than I had been doing. This worries me, since I'd been so careful previously, I'm not sure I can accomplish this greater standard of care.

5.0 out of 5 stars Some issues at first but it’s been corrected.
Reviewed in the United States on February 27, 2020
Update to my review—I received the new replacement unit today and the new thermostat is working. Amazon and Vivosun quickly resolved my issue and sent a replacement that took only two days to arrive. Thanks to both Companies for taking care of this! I’ve increased my original 3 star review to 5 stars!

Testing it out—you set the thermostat to a temperature, I.e. 74 degrees (Fahrenheit) and insert the temperature probe into the soil or growing medium. If the probe is reading less than the desired temperature it will run the heating pad until the medium is heated to the temperature you want it.

My new replacement unit shows all this in degrees Fahrenheit, and let’s you program the temperature in Fahrenheit. The first “defective” one only showed it in degrees Celsius and could only be set to temperatures in Celsius before displaying the Fahrenheit Temperature.

The new heating pad, like the previous one works, no issues there. Keep I’m mind though it plugs into the thermostat, the thermostat does not set or regulate the temperature of the heating pad. The heating pad will be warmer than the temperature displayed on the thermostat—as the thermostat is only monitoring the temperature of the soil or growing medium. Once it reaches the set temperature it shuts off power to the heating pad.

My older review from earlier this week dealing with the defective thermostat:

I am in the process of returning the combination seedling heating pad and thermostat because the thermostat doesn’t work. The unit I received did not supply power to the heating pad. I had set up everything as per the instructions and kept an eye on it, noticing that the “heating” light never came on with the pad plugged in. So I took a non contact thermometer and checked the pad temperature—it was room temp and nothing more, then plugged in an outlet tester (in the photos) to check the thermostat plug in for the heating pad and there was nothing. I’m assuming it’s not wired correctly and contacted Vivosun’s support via email. I emailed them Sunday and have not heard anything back yet, so I decided to exchange the item through Amazon—which had a very easy and efficient way of handling the exchange—they are sending me a new one which I hope works correctly and I have to drop the defective one off at my nearest Kohl’s store customer service department to be sent back to Amazon.

I’ll have to update this once I get the replacement unit and can better judge the thermostat. The heating pad works very well and I had to manually regulate the temperature to sprout my seeds. It seems very heavy duty for the wattage it works on and should last a few seasons. I know it’s offered separately from the combination set I had ordered.

If it had worked right, the thermostat was easy to set to the temperature on and I like how the probe is designed. The only other complaint I had was that you have to set the temperature in Celsius—but it will display the temperature in Fahrenheit. Some conversion work needs to be done if you want to set it at 80 degrees F for tomatoes.

Had it worked and controlled the heating pad, had Viviosun contacted me back with their advice on what to do (it’s rumored on Facebook they are not responding to emails possibly because of being located in China and not working due to current events), I would have given this a 5 star review and written how well it works. Hopefully I can post that review once I get a properly working replacement.

Reviewed in Canada on March 14, 2024
I recently purchased the Heat Mat and Digital Thermostat combo, and I couldn't be more impressed. This product is a game-changer for anyone in need of precise temperature control for their reptile terrariums or seedling propagation.

First and foremost, the heat mat provides consistent and gentle warmth, creating the perfect environment for my plants or reptiles to thrive. The size options available make it versatile for various terrarium or seedling tray sizes.

The digital thermostat is incredibly easy to use and allows me to set and maintain the ideal temperature with pinpoint accuracy. The large, clear display makes it easy to monitor and adjust settings as needed, ensuring optimal conditions at all times.

Installation was a breeze, thanks to the detailed instructions provided. I appreciate the durable construction of both the heat mat and thermostat, ensuring longevity and reliability.

Overall, I highly recommend this Heat Mat and Digital Thermostat combo to anyone looking for top-notch quality and performance. It's a five-star product that has exceeded my expectations in every way possible!
