VIVOSUN Digital Heat Mat Thermostat Controller, 40–108 ºF 1000W for Reptiles, Seedlings, Germination, Incubation and Fermentation

I am very happy with these thermostats. I am using them to control Vivosun heat mats.. The combination works flawlessly. The temperature control is acceptable and with the controller, very adjustable. They do not heat quickly. For me, that is ideal. They do not draw a lot of power while warming, and seem to not take much electricity to maintain the temperature once it reaches the setpoint. That is excellent. I have used Vivosun heat mats and thermostats in the past and expected them to still be high quality. That is exactly what I found. Very easy to use. I have never had any problems with them and they get water all over the mats almost constantly with timed watering. No issues at all. I keep the thermostats elevated out of the water spray, so the critical connections always stay dry. I am a fan of Vivosun products and will purchase them in the future.

I read some reviews saying the thermostat did not read true. I took a chance and bought one last month for my seedling heat mat then ran a test when I got it. I set it to 80 for my mat with a cup of water on it. Put the thermostat thingy in the water and waited testing every so often. The thermostat read consistently .2 higher than my instant thermometer so good there. It shut off at 80.2 and turned back on at 79.5 - perfect. I was happy so I bought the second one I needed and it tested the same. I am very happy with these

Works fantastic for my seed starting mats, great for gardeners.

I use for sprouting plants and also to warm compost worm cocoons so they hatch sooner. Can control 2 heat mats at a time if you use a cord with 2 outlets, might possibly control more, but I haven’t tested that yet. I plan to buy 2 more mats to see if it can handle 3-4 mats at a time to save money. Even if it can only handle 2 heat mats it’s worth it. The only down side is that it fluctuates 4-5*F. I’d prefer if it was only 1-2*F. I’m not sure how long this last running 24/7 year round, but so far after a few months it’s working well and my worm cocoons hatch 1-1.5 weeks faster than those not on a heating mat. I use these indoors and our home is heated 69-70*F, heat mats are set to 80*F. If it can last a few years it’ll be worth the investment and if I can handle 3-4 heat mats it’ll be even more so. Also, if you heat mats from another brand this will work with them, no need to buy their brand of mats. I did buy their heat mats since mine only heat 1/2 the length after being in service for over 12 years. The original ones I purchased are no longer available or I would have bought those again because of longevity. Overall a good purchase…so far.

Received mine two days ago and promptly hooked it up only to discover that the LCD readout only functioned partially. As it stands I am unable to see the actual temperature readings or know for sure if I have set the correct temp on the unit as only parts of the number grids will display but not enough to know exactly what number you are setting. Aside from the bad display, the unit seems very basic to operate and the included instructions were sufficient. Like many others, I must have gotten a bad unit. EDIT 01/01/2017 I was contacted by the seller shortly after posting my original review and they offered to replace the defective unit for me. Upon receiving the replacement unit with expedited shipping, I am happy to say that the display is working perfectly and it appears to be maintaining the temperatures much better too. I'm very satisfied with how things were address and resolved.

Pretty impressed with the temperature control from this controller. Keeps accurate temperature within 1°F.

works pretty good , although mine all of a sudden stopped putting out Fahrenheit , it only gives me Celsius . so, I have to do conversions to use.

The instructions for adjusting the settings weren’t very clear, but watching the video helped. With consistent temperature, my seeds sprouted 5–10 days earlier, which means I can start them later next year.
