With the EHEIM thermocontrol-e heating element, your fish will enjoy the ideal temperature with even greater precision in every aquarium. Often, the simplest ideas are the most effective, and this holds true for the aquarium heating element. It is designed to be easily submerged in the water, providing efficient heating just as it has for many years. However, the EHEIM controller heater has evolved into a highly advanced thermal device. The temperature can be accurately set and is measured with enhanced precision, maintained consistently thanks to advanced electronics. The special laboratory glass coating not only increases the heating surface but also serves as a heat shield, ensuring an even distribution of warmth. Whether you need to heat a 20-liter or a 1200-liter aquarium, there are 10 different sizes available.

Advantages of the EHEIM control heater thermocontrol-e

  • Accurate temperature adjustment from 20 to 32 °C
  • No need for readjustment
  • Control accuracy of ± 0.5 °C
  • Stable temperature maintenance
  • Control lamp indicates heating status (red: heating; green: temperature achieved)
  • Fully submersible and waterproof
  • Equipped with dry-running protection (Thermo Safety Control)
  • The glass coating enhances the heating surface and ensures optimal, uniform heat distribution
  • Convenient cable length of approximately 170 cm
  • Includes double suction holder
  • Available in 10 sizes for aquariums ranging from 20 to 1200 liters
  • Compatible with both fresh and saltwater
  • Exceptional safety and reliability - 3 years warranty

Combining precision, comfort, quality, and safety, the EHEIM thermocontrol aquarium control heater is a significant advancement over the original heater designed by engineer Eugen Jäger decades ago. Before its invention, maintaining an appropriate water temperature was a challenge, often employing complicated or unconventional methods, such as placing the aquarium in sunlight or near a heater or stove.

The thermocontrol-e represents the latest electronically controlled version of this legendary heating element. You can finely adjust the temperature between 20 and 32 °C with a control accuracy of ± 0.5 °C, ensuring a steady temperature. A control lamp will indicate whether the heater is active. This heater is completely waterproof, can be fully immersed, and features dry-run protection (Thermo Safety Control), making it suitable for both fresh and marine water.

One of the notable innovations is the glass coating, which:

  • Increases the heating surface,
  • Consolidates the heat, ensuring optimal and even heat output, and
  • Acts as a heat shield (safe for aquarium inhabitants to touch).

This coating is crafted from special laboratory glass designed for research purposes, ensuring it is free from pollutants that could leach into the water. It is resistant to chemical and biological substances, is crack-proof, and can withstand extreme temperature fluctuations, such as those that may arise during water changes.

Clear Protection and Easy Installation
Model: iPad 9th/8th/7th Gen 10.2-inch
I’m really happy with these screen protectors overall. The glass feels high quality and provides good protection without affecting the clarity or touch sensitivity of the iPad screen. The installation process was straightforward, and I didn’t have issues with bubbles as long as I followed the instructions carefully. Once applied, it looks clean and fits the screen well. Overall, this is a reliable and simple way to protect your iPad screen while keeping everything looking clear and responsive.

Super great screen protectors, but bad prep materials.
Model: iPad A16 11th 2025 /10th 2022, Model: iPad A16 11th 2025 /10th 2022
I got an iPad A16 for my birthday and wanted some affordable but durable screen protectors. These are great, but there were a few problems I had. Pros: These fit perfectly, don't shatter or chip easily, and are a very good price. Cons: The dust absorber stickers that come with the kit aren't even close to sticky enough (I had to use just normal stickers, which was fine). The alcohol prep pad was pretty dry too (I had to use a different alcohol wipe). The screen protectors themselves are amazing. You can trust them to keep your iPad safe. Just be prepared to DIY the prep a bit. I would still reorder and recommend these!

Love it!!
Size: Iphone 17, Color: Light Blue
I got the Miracase Magnetic iPhone 17 Case in light blue, and it’s excellent. The case fits my 6.3-inch iPhone 17 perfectly and works flawlessly with MagSafe chargers and accessories. The military-grade protection gives me confidence — it’s shockproof, scratch-resistant, and feels very durable without adding unnecessary bulk. I also love that it comes with a screen protector included. The anti-fingerprint translucent matte finish keeps the phone looking clean while providing a nice grip. It’s easy to install, feels premium, and the color is subtle yet stylish. If you want solid protection with MagSafe compatibility and a clean, modern look, this is a great choice.
