Works very well, and gives you the option for C or F. Only thing i might ask for its for it to have a back light.
Great thermometer for the price! By Michael on 8/6/2014

Easy to install, everyday when I check it, I get an accurate reading. Very affordable and small display for limited space in the sump area. 2 thumbs up!!
Does what it says By Nicholas on 5/18/2014

Simple and straight forward product works right out of the box. Only had in my tank for about a week but seems to be doing exactly as advertised. Great to check that temps are the same on the opposite site of your tank from your heater. The suction cups used internally and externally seem to be the best ever. Very low profile on the outside of my tank
Cheap and Digital By Tom F on 5/5/2014

Digital thermometer on the cheap that is accurate enough for what I need it to be. This is better than using glass stick thermometers.

Great price for digital thermometer. Better than the glass alternatives. Cheaper than all other digital thermometers I have found. Accurate enough for my needs.
Great thermometer By Reefer on 4/9/2014

This thermometer works perfectly. I have only had it a few weeks and really like it so far. It's easy to read and at least in this initial stage it works like a charm.
Not reliable By Eric on 3/17/2014
Eric wouldn't recommend this product to a friend
I've owned this thermometer for about a year and in the last 6 months the screen constantly flickers on and off. When it comes back on the temperature usually changes by over 5 degrees. I doubt the temperature fluctuated that much in a few minutes. It never seems to stabilize back out either but stays stuck either really high or really low.

This is a great and simple unit that takes seconds to set up and allows you to verify your temp at a glance.

I trust this and easy to read By Alexandria on 4/18/2013

Purchased this to use for water changes and as a main thermometer in my tank. (The long cord makes it super easy to move from my tank to the new water.) It matched up with my old thermometer's read out so I trust that it is right. It's nice to have big numbers that are easy to read.
As someone else mentioned a backlight feature that could be turned on or off would be nice.

I had a rash of bad heaters and needed a second probe too confirm accuracy and steady temp. Works perfect.

I wanted a digital thermometer with a nice sized LCD display so that I could quickly glance over and see the temperature, and this works nicely.
Inaccurate +4 degrees By Trevor on 11/25/2012
Trevor wouldn't recommend this product to a friend
My thermometer consistently reads 4 degrees higher than my actual water temp. My heaters are set to 78 degrees and I've verified that other thermometers read the temperature at 78. However this JBJ thermometer reads at 82.1.

Does not Last long enough By Alex on 10/16/2012
Alex wouldn't recommend this product to a friend
I think I have been through 5 of these within a few years. I have one that does not work anymore and 2 that are about 10 degrees off. It seems to lose its calibration and there is no way to reset them. I think I will try another brand for my next thermometer. It was great when it work correctly and a good price. I just wish the usable life lasted a little longer.

Great peace of mind for only 10$. This is a great way to double check those sometime troublesome heaters.
Cheap and very useful By Kyle on 5/19/2012

I primarily use this to monitor the temperature in my 90 gallon display tank to make sure that my lights aren't heating up the water too much. It works very well, and for the price I don't think you can beat it. I also pull it out of the DT and use it to check the temperature of my replacement water when doing water changes. It has a great double suction cup mount that allows you to quickly and easily detach the digital readout. I like that a lot because I have it mounted to the back of my tank glass so it's out of sight but I can still detach it and read it with no problem. If you don't have a thermometer yet for your tank, do yourself a favor and pick one of these up.

I keep one of these in my sump as a check against my controller temp sensors, and have another for mixing water. I'm ordering a third for my QT.
Would only be better with a backlight.

I bought two of these (one for my sump and one for my saltwater mixing bin). I like the fact the cord from the probe to the display unit is long enough for me to put it wherever I want. No complaints.

I use this probe to make sure the temperature in my tank is correct and steady. This is by far the simplest way to tell temperature

I use this on my 125 gallon reef to make sure its at the temp it should be. I use a glass thermometer also and they are exactly the same temp. Its easy to put the prob in the sump and put the display on the side of the tank for easy reading.
