We needed to heat a small hospital bowl for a wounded Betta and wanted something that we could use again to heat his larger 5.5 gallon tank. It works so wonderful and is reliable. The preset temperature feature is nice too. When I put it in a 2 CUP bowl to see how hot it would get, the highest temperature reached was 80 degrees. This being said, I trusted it for a larger bowl. I have only had it for a day but so far, for what we payed, even if it does stop working, it is okay if we have to replace it-- as long as it lasts longer than our other small heaters from Aqueon, which both stopped working after a few months.</span> <div class="bvseo-pubdate">Date published: 2017-12-22</div> <meta itemprop="datePublished" content="2017-12-22" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="http://schema.org/Review" data-reviewid="177773031"> <meta itemprop="itemReviewed" content="Top Fin&reg; Betta Aquarium Heater" /> <span itemprop="reviewRating" itemscope itemtype="http://schema.org/Rating"> Rated <span itemprop="ratingValue">5</span> out of <span itemprop="bestRating">5</span> </span> by <span itemprop="author">MsPattycakes</span> from <span itemprop="name">Awesome heater</span> <span itemprop="description">We have a 1 gallon tank for our Betta and this heater works perfectly.

The size is small and manageable and the pre-set temp is an awesome feature. I have a 2.5 gallon tank and got the 20w heater. The temperature never goes down under 77F. It is often steadily around 78.8F. I've never seen it over 79F in my size tank.

In 2.5 gallon betta tanks, they keep the water between 80 and 82, perfect for my jungle fishies. In bigger 5/5.5 gallon tanks, the water stays around 77-78. I really like the indicator light, the slim design, and that it can be used vertically, horizontally, or even under substrate. A couple of my bettas like to lay on top behind the cord so they can be warm while being lazy.</span> <div class="bvseo-pubdate">Date published: 2017-09-15</div> <meta itemprop="datePublished" content="2017-09-15" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="http://schema.org/Review" data-reviewid="135584090"> <meta itemprop="itemReviewed" content="Top Fin&reg; Betta Aquarium Heater" /> <span itemprop="reviewRating" itemscope itemtype="http://schema.org/Rating"> Rated <span itemprop="ratingValue">4</span> out of <span itemprop="bestRating">5</span> </span> by <span itemprop="author">Minimanminh</span> from <span itemprop="name">Great size</span> <span itemprop="description">I brought this last week and it's great it says for 2.5 max but I have 3.5 and it works just as well but it did take a few days to warm up my tank and sometimes it just does nothing and no heat</span> <div class="bvseo-pubdate">Date published: 2016-11-22</div> <meta itemprop="datePublished" content="2016-11-22" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="http://schema.org/Review" data-reviewid="176213086"> <meta itemprop="itemReviewed" content="Top Fin&reg; Betta Aquarium Heater" /> <span itemprop="reviewRating" itemscope itemtype="http://schema.org/Rating"> Rated <span itemprop="ratingValue">5</span> out of <span itemprop="bestRating">5</span> </span> by <span itemprop="author">Just another Jack</span> from <span itemprop="name">Excellent</span> <span itemprop="description">Even though I have a three and a half gallon tank.
