Rated 5 out of 5 by Grover71 Good Heater
I bought the 100 watt. It's fully submersible, so you can make the minimum level line as far up or down as you want. No maximum level line, so don't have to worry about that. I've had no problems with it at all, and I've found it to be very accurate when making small adjustments at a time. I'd buy another.

Rated 1 out of 5 by alc42 Never even turned on
I purchased two of these 50 watt heaters from my local store, and neither one ever turned on. Followed the directions perfectly (submerged for 30+ minutes before turning the heater on) and nothing ever happened. No indicator light, no heat, and overnight the temp in my tank DROPPED 10 degrees.

Rated 4 out of 5 by croftoniandude So far, so good
I purchased the 200W heater for my 45 gallon tank to replace a Marineland which wasn't even a year old. My previous heater (150W) never did a very good job, and often struggled to maintain 79 degrees at nearly the maximum setting. I followed the setup instructions and within 24 hours, I noticed superior heating performance with this heater. And my thermometer reading are almost perfectly in sync with the temperature the heater is set to.
Thankfully my fish and plants are doing much better now that their habitat has been restored.
I can't speak to the durability of this product, but just on performance thus far, I would highly recommend this product to anyone looking for a heater.

Rated 5 out of 5 by Fishwich Works for me
This heater works just great. It will adjust to your preferred temperature accurately. That may not seem like much until you have one that will not adjust at all. Keeps the aquarium at an even temperature and has not caused or had any issues at all. Good product.
