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

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

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

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

I used it to keep my Kombucha at a constant temp. I purchased it November of 2018 and just threw it away this morning. It showed a power fault, I unplugged the heating mat and the fault remained. So now I need another one. Don't know if I will purchase the same thing again. Until it failed it worked beautifully. It held the set temperature to within half a degree, it brought the liquid up to temp within a reasonable time. the only thing I would found problematic was the suction cup holding the temperature probe to the container was easily dislodged. Seven months continuous service for sixteen dollars is not a bad deal, but I'm going to see if there is something out there a bit more durable.

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.

Simple, easy to understand instructions for set-up.

Bought this for my leopard gecko and it is working good, fluctuates slightly above and below my set temp but seems to maintain the temp fairly well. My gecko seems to like it so that’s all that matters! Good buy.

I bought 3 of these Vivosun thermostats. 2 arrived in working condition but the third came right out of the box unable to turn on. First thinking it was my outlet, I tried many throughout the house. The red display wouldn’t even light up so I am not sure with the issue. I am extremely frustrated because I paid an extra $10+ shipping for “next day delivery”. I did receive the item but the item is defective. I needed this thermostat ASAP because my snake needs its heat lamp to be calibrated and its winter. Didn’t pay an extra 30 dollars for something that doesn’t work, not worried about the money, more frustrated at the fact that the product doesn’t even turn on, needless say function. Hoping the other two don’t die on me as well… -UPDATED 1/20/2019: Vivosun reached out to me and offered to send me a new thermostat in order to replace the one that didn't seem to work. Once received, I tested it out and it seems to work fine (Same as the other 2 I have). I appreciate quality products just as much as quality customer service so thankful for the team over at Vivosun. Will do business with them again in the future.
