  • Keeps the temperature pretty constant
Size: 20W
It's small and I like the display of the temp while using a single device instead of a warmer and thermometer. For a small tank it's convenient because it doesn't take much space. What is didn't like is that I notice jumps in the temp reading - + 1-2 degrees suddenly. But besides that it seems to work just fine for over 2 months now ... show more

  • Accurate Temp Gauge
Size: 20W
This keeps the temp exactly at what it's set to and the read out is accurate with my other gauges I have in the tank. Really nice and easy to use! I haven't had a problem with the suction cup on the mini heater like others say but even if it just hung in the tank it would be fine. Great value for money honestly. ... show more

  • Nice adjustable micro heater
Size: USB-10W
Happy with size and adjustable function. I was skeptical and micro managed temp for a few days but I was able to relax with it performing perfectly for a 2 gallon with air flow!

  • USB fish tank heater
Size: USB-10W

  • Works great!
Size: USB-10W
This heater is tiny but mighty and does its job very well without taking up much space. The only downside is the suction doesn't work.

  • It WORKS!
Size: 25W
This heater worked perfectly! I put it in a bucket first to see how close the temp. was, it was 2 degrees off, so I set it accordingly, it has worked perfectly!

  • Hard to understand directions
Size: USB-10W
Not having good directions on how to use it Pictures would help and more clear directions

  • Worked for a temporary use
Size: USB-10W
Suction cup was great. Good value. Perfect size. Loved the USB power!!! So I would give 5 stars but the memory function was definitely defective. So I ended up ordering the 25 watt which although does not have USB works wonderfully. And I definitely plan to use the USB one in emergency situations as the memory function won't be a issue if it was a emergency I feel I would be very attentive of it. Overall ok product for a emergency and temporary solution like I needed. ... show more
