Came quick and works well.
Mine works just fine and my snails love to crawl on it.
Works just fine. No issues.
I have one of these in every single tank I own. They work great! I didn't like the green area at first, but like today when its close to 0 F outside, I like to be able to quickly glance while I walk by my tanks that are by windows first thing in the morning. I'm not looking for a specific temp, just to see that its not fluctuated out of the green zone. So in the end, that's a feature that I have come to appreciate. These are $8.99 at my local fish store and $4.99-$6 at my local Petco's. So while you're ordering from Cory, don't forget to throw one or two of these in your cart before checking out. That's what I do.
