Review: Keeps things warm - Works as expected. I use it for my chickens. I have their water in a 5 gallon bucket with those little orange nipple valves installed on all sides. I have this thing cranked up to 90 degrees and amazingly it keeps the water and the valves from freezing even when the temp dropped down to -9 degrees F. outside. So the chickens can get to their water on days when a water bowl freezes solid inside of a couple hours.
Review: Great heater - I got the 50W for my 7.5 gallon tank. I’ve never had a problem with this heater. It’s always heated my water to my desired temperature. The only thing I would suggest is to monitor your water temperature within the first couple hours of introducing the heater as it needs some time to adjust.

## Questions & Answers

**Q: Will this work well in my 40 gallon red eared slider tank?**
A: We use it in our 60 gallon for our red eared and it works great. Have no problems. I truly think it is the best heater we have gotten. You can maintain the temp in the tank very easily.

**Q: How can I get replacement suction cups?**
A: Search Amazon

**Q: Is that ok get 200w heater for 10 gallon tank?**
A: The 200W  heater is too powerful for a 10 gallon fish tank,  choosing 50W or 100W will be better.

**Q: Do these have some kind of warranty?  I got mine in September and it broke today. Just cracked and stopped heating.**
A: I do not believe they have any warranty. I’ve had no problems with mine. It’s extremely odd for them to crack unless possibly it cracked from shock or maybe you were changing the water and forgot to unplug it because if the glass gets heated while the elements heating up and then you add water it could crack it.
