Works exactly like I wanted

Order came quickly and in good packaging. Before I used this I was concerned about it being too hot, but after I plugged it in I felt that it was the perfect temperature. I am currently using it to start peppers and it seems to be working great. Vivosun products are the best!

I appreciate an item that can be used for multiple things. Right now, this sits underneath a cooling rack to keep my sourdough starters warm on colder nights. This spring, I'll likely be using it for seed starting as well. My only complaint is it would be nice to have a switch to turn it on and off rather than plug it in or unplug it.
