It is a little difficult to dial into an exact temperature, the dial to adjust the temperature warmer or colder is a little difficult to turn and it’s difficult to read exactly what the temperature is supposed to be at, it takes a little trial and error to get it at the temperature you want it to be at ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars It works. *by N***. on Reviewed in the United States on July 26, 2024* The media could not be loaded. When heating the coils turn red which I think is pretty cool. I haven’t tested it with a thermometer but I tell the temp difference with my hand. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/632059964-aquarium-heater-50w-100w-300w-submersible-glass-fish-tank-heater](https://www.desertcart.hr/products/632059964-aquarium-heater-50w-100w-300w-submersible-glass-fish-tank-heater) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-09-23*
