There seems to be a 2 degree difference between the thermostat and a separate external thermometer I use, but that is easy enough to adjust for. My only other complaint is having to reattach the suction cups to the wall every few weeks. With any sort of flow, they seem to lose their hold.
So far so good By Mascis on 3/30/2013

I don't have a controller, so these make it easy to check my temp on an ongoing basis. It's not glass, so there's no worry of explosions. And a small alarm sounds at a drastic temp change. like when the probe came out of the tank accidentally one day.

I have a couple of the larger units in my 57 gallon reef, and they do great at maintaining temperature. Unfortunately, after trying 2 different units, the small 50W unit is not large enough to maintain temperature in my nano tank. It will only raise the temperature by about 4 degrees in a 12 gallon tank.

This is by far the best heater I have purchased. I have had expensive heaters and cheap heaters, but this heater does it for me. It's easy to operate, the built in alarm for temps too high or too low is a life saver (literally for your fish) and it's not glass so I don't have to worry about it breaking in my tank or sump. I have one in each of my fish tanks and have gotten a few friends to buy them too!

I have both a 150w and 100w. Both have been working great for 6 months now. I have been using a temp probe and they are as accurate as the claim. The built in remote temp sensor cord could be longer.

I have this in my 29 BioCube and it works great. I love the easy to read digital control. It's easy to tell if the heater is on or off and what temp the tank is at. I'm going to get another one for my water changes.

Titanium heater that is easy to setup with a nice digital read out & controller that sits outside of the tank. Worried about reading your heater correctly? Not a problem with this heater, which also doubles as a temperature gauge. I have 2 x 200 watt in my 75 gallon + 30 gallon sump and they work perfectly.

Purchased this a few months ago. Have used it for a few different things, for starters I used it to maintain an even 80 degrees F in a Rubbermaid tub I was curing rock in. Had no issues and kept the water exactly where I wanted it. I later removed the heater and rinsed it off and put it in the main tank. The thermostat portion of this heater is on its own wire so you can place it somewhere reasonably far away from the heater itself.
I think this is a benefit because you can use it in a different flow area to make sure the heat is being distributed around your tank. The digital read out is also a nice touch, I prefer it to the older spin dials I've used in the past.

This heater sat on my seahorse tank for one whole year. I keep my tank at a low temp, so it never turned on, but I kept it on there just in case my tank happened to get under 72 degrees one day. One day I took it out and put it inside of a smaller tank to test to make sure it was working. After acclimating it and turning it on, much to my surprise, I dipped my hand in the warm water only to be electrocuted. Thank god this terrible item never turned on inside of my seahorse tank, otherwise I'd have some floating fish. Don't get this heater.

I bought the 300, and Im happy with it so far. It does have an LED controller which is nice. It has been keeping my temp where I want it. I wish they had a bigger heater since my tank is a 120 gallon not including the sump. But this seems to be doing the job.

I bought the 150w version for my 40 breeder and it's been working perfectly thus far. Love the digital readout, made me feel much more confident when setting my temperature in comparison to the dial-set heaters I've used in the past where you just sort of guess and check.

Devin wouldn't recommend this product to a friend
What is an acceptable failure rate for a heater? Especially when the failure is water getting into the heater's electronics and creating an electric current in your tank? Is 1 per 100 acceptable risk? Unbelievable! I bought two of these 6 days ago to cook dry rock and came home this evening to check on the tub, put my hand in the water and was shocked. Water was in teh electronics. This heater had nothing done to it than taken out of the box, put directly into the water, appropriately hung and did not move until this happened. BEWARE!!! lucky I didn't use this unit in my tank and only to cook rock. Will NEVER Use this product when there is anything to risk.
Compact heater By Kerric on 4/2/2012

I use one of these hooked up to my Apex Jr. controller. The controller turns the heater on and off (I keep the heater temp controller turned all the way up) and it works well. Before I had the reef controller connected however the heaters controller was in use and worked well but that was only for about a month. This heater (the 100w model) is VERY compact and sits in the return chamber of my sump. I am pleased with it so far.

I was looking for a short heater as I did not have much space in terms of length and this fit the need perfectly. Seems to be working correctly so far. The only complaint I have is I wish the control unit had the wires coming out on 1 end .. wouldve made it easier to hang is nicely somewhere .. for now Ive just stuck it on somewhere. I didnt find the hook that came with the item very useful but it might fit the needs of others better
Simple By Sergio on 3/6/2012
Sergio would recommend this product to a friend
I bought the 300 watt model and placed it in my 90 gal tank. I’ve been using it for about a month now. With my metal halides I don’t expect to use the heater much during the day, mainly at night. I like how simple it is to use, simply set the digital temp and forget it. I really like that the temperature probe is separate from the heating element. I placed the heating element on intake of my sump and my temp probe in next to my return pump. The unit keeps my temp right where I set it and even sounds an alarm when the water temp gets too high, around 86 degrees F. I found this out while holding the temp probe tight in the palm of my hand for a while testing it the temp probe really worked. Don't know if that’s adjustable but nice to know it’s there.

These heaters are well built and come in a nice compact size which allows for them to be easily used in the sump. However I wish they could find a way to combine the cables from the heater, the controller and the probe.

I have both a 50W for my pico reef tank and a 100W for my freshwater, this heater has given me no problems so far, I plan on updating soon, however for the money you absolutely cannot beat this titanium heater, works reliably even when the temp probe is off by 1 or two degrees it is constant so you are able to set it. I would recommend to anybody starting out and looking to update at a later date.

I sure hope all of these aren't as bad as the one I got. It won't maintain temperature, the controller constantly turns the heater off. I have to go hit it a few times to get it back on. This is the second time in a month that it's dropped my freshwater tank to 70 degrees when it's set at 79! It just turns itself off all the time.. Would never buy one again.

It's nice to have upgraded beyond a glass heater. This product has relatively long cords. It recalls the temperature setting after having the power cut.
I have this set up on my ReefKeeper Elite which cuts the power to the heater anytime the water gets too warm. I reccomend using a controller like the ReefKeeper with ANY heater.

I bought this heater as part of my yearly ritual of replacing my heater in the tank. I've had 2 heater problems in the past and both stuck on! It nevers fails that Im away when this happens! This heater was great and with the separate temp probe kept the tank within a tighter window than previously. However 2 weeks ago this one stuck on as well. I think the product is great but after only 8 months, I got less time out of this one. I still reccomend, but I will be purchasing a monitor shortly to keep the next heater in check. After three heater malfunctions and hundreds of dollars worth of livestock losses its time. Cool heater! Best Ive had so far.

Best titanium heater for the price. Easy to use digital temp control. Comes with separate heat sensor to give you a more accurate reading and can be placed apart from you heater to give you a more accurate reading of the temperature in other parts of your tank besides directly next to the heating element. Could use a longer length of cord for both the temp probe and the heater, but for the price I'm not going to complain too much.

Best titanium heaters out there for the price. But in an ideal world, the temp alarm settings would be adjustable and the auto kill would be a separate sensor built into the tube, so as to prevent overheat in run-dry situations. A couple more inches for each cord would also be nice, but this is not a perfect world. :)

The heater is easy to set and adjust the temp so far it has been holding my tank around +-1 degree. It is extremely nice not having to remove the heater to adjust it. Others have said the cords are a bit short but 32 inches from control head to heater is perfect for my setup. I just wish that they would have put the power plug on the top of the controller so that the cord to the heat would come out of the bottom. Doing that would give some people a few extra inches but there again it depends on your setup

I previously owned Marineland Visi-Therm Heater for 1 of 3 of my tanks. I have Marineland Stealth Pro’s for the other 2. I have had limited luck with these heaters. When the Visi-Therm Heater went out, I lost my Philippine Yellow Tang, Swissguard Basslet, and Hi-Fin Goby, I decided it was time to change brands. I read the reviews on different heaters and then turned to BRS and I decided to give the Finnex 150W Heater with Digital Controller a try. I really like this heater. It does an excellent job with a much smaller footprint (~7 ¾” L vs. 13 ½” L) and uses 50 Watts less than the heater it replaced. Purchased on 2/8/2011 and plan on purchasing these as a replacement when the Stealth Pro's burn out.

I have this heater in addition to the HPS line. This is by far the better of the two. The external controls allow for easy adjustment without getting wet.
The only change i wish this had was a way to silence the temperature alarm. I routinely use this heater to heat my RO/DI water before using it - if the temp of the water is below 65, there is a constant alarm with no way to turn off. Its not too bad in my garage, but if you have this in your house, you're going to get annoyed quickly.

Have been using on on my system for the last year it is a good heater with a nice temperature display on it. the only problem with it is that I am using a controller to control my temperature and every time the heater gets powered on there is a beep so if you are planning on using this heater with another control I would recommend the one with the analog control.
