Review: Nice heater - Small but works well in our tank. Suctions work great, once positioned correctly. Thermostat’s easy to set and keeps temperatures at that setting.
Review: Small but sweet - I've only had this heater for a week but so far it is working spot on and keeping my tank at the perfect temperature. It's been many years since I used an aquarium heater and I can see great improvements in the technology. I particularly like the small size and that it's submersible all the way under the water. The dial and control mechanism are on the outside and have a nice digital display, and I like all the built-in safety features that come with this particular model. For now I truly give this five stars. Hopefully it will hold up over the many months to come and unless something goes wrong I will keep this review at five stars. I highly recommend this product.
