Great product!

Does pretty much what you would expect and does it well. My only complaint is that the heat mat plug (same brand) doesn't really like to stay in the socket, so it gets bumped out really easily. Because of the design of the product it's not easy to zip tie it together to hold the plug in.

works as described

First year starting from seed and used this for the heating mat under the tray germinating my tomato and pepper seedlings. It worked as described and the setup was straightforward.

Worked fine

As others stated the plug in was loose. Still worked well enough. We spread the prongs on the plug a bit to get a tighter fit.

Loose Outlet

I finally dug deep and bought a real seedling heat pad and controller. Unfortunately, the model I bought had a loose outlet, which is a serious fire danger. It also had one LED in the display blink out after a week or so. It did work, but I never trust a loose outlet. GMS was good enough to send me a new controller, which unfortunately also had a loose outlet, so they refunded my money. GMS has always given great service; I have no beef with them and will continue to use their great website, but I will have to find another controller elsewhere.

Poor Quality

It seems to work OK. One of the LEDs on the display quit working after a few days. Worst of all, the socket that the heat mat plugs in to is loose. It draws 8 amps, so a loose socket is dangerous. I frankly don't trust the UL certification mark, as the Chinese have learned to put false UL or Intertek mark on electrical products. Returned for different brand.

Love It

First time to use a heating mat as i never thought it would make a difference, but I was wrong. The night time temps were to cold for this time of year and seeds were not germinating, so i broke down and ordered a mat. I am so happy I did. I replanted seeds and put on the mat and had great results with germination

Thermostat for Seedling Mat

Seemed to easy to set and worked fine. But, only used for a couple of weeks so far. Hope it has a good life expectancy which will tell the tale. Check back in a couple of years!!The temp sensor was a bit large and the wire just a bit too stiff for my fragile 4x6 seed starting containers but with proper set up, stayed in place and worked.
