Customers say
Customers find the thermostat works well, particularly in incubation areas, and appreciate its ability to keep temperatures within 1 degree. The device is easy to use and set up, and customers consider it worth the price. They like its accuracy, with one noting it’s accurate to an integer number of degrees, and its alarm functionality. The display brightness receives mixed feedback, with some customers finding it too bright.

Great for regulating Heat pads
I bought this style thermostat specifically for use with a 30-40 gal ZooMed heating pad. So far Iâve had it for 3-4 months and itâs worked flawlessly.The length of the wire connecting the thermostat probe to the unit is ample enough to submerge the probe into the substrate a few mils above the center of the heating mat (to get an accurate read of the temperature of the substrate) then run the probe data line to a corner of the tank and up the corner out of the tank, keeping it very hidden, my tank is 40Gal too and it runs from basically the center so no issue really.The display text is large and concise, it reads the current temp and the set temp, wether the heating or cooling element is on or off. Programming the unit is fairly intuitive, as it has an alarm (never tested that), heat and cooling settings and the temperature setting. Heating turns power to the outlet on the unit on while the probe reads a temp lower than the desired temp and Cooling turns the outlet on when the temp is above the desired temp. Itâs accurate to an integer number of degrees (Fahrenheit or Celsius, you can switch between the two seamlessly) and the display is backlit very well, in fact itâs so bright that at night you may have to cover it because it will act as a mini night light.So far the only downside Iâve encountered is that it wonât directly support multiple heating or cooling devices a once, only having one power outlet. However this can be partially rectified by plugging in a surge protector strip and then plugging in either heating or cooling devices only into the strip. Be warned though the total power consumption of all the connected devices, in this manner, in watts, cannot exceed the maximum power rating for the Zoo-med digital thermostat. In fact just Incase of a surge you probably should leave a 15-25% space for power draw so you donât fry the thermostat. Also donât do this if youâre not a professional.

Great for nano fish tanks.
It’s quite difficult to find a small heater that also has a thermostat for small shrimp bowls and the like. The few that exist are on the large side and failure prone or generally inaccurate. The solution is a simple 5W or 10W always-on heater and an external thermostat. The issues are:1) Most aquarium external thermostats are expensive and have more features than needed for a simple setup.2) Most reptile heaters have a sensor that cannot be submerged in water (without sealing it somehow).This unit addresses both. I have several and have used them for many months. They work great. Setting the temp is a little annoying, but how often do you do that? It would be nice if the back light could be disabled, but it’s handy to be able to check the temperature at a glance. All of mine seem fairly accurate (within a degree or two). It seems to have 2 degrees of hysteresis (if set to 75, it will turn on at 73 and off at 75), which seems to be a reasonable compromise. Having a separate sensor lets you place it in an optional position to get an accurate reading (away from the heater).

Does it’s job for heat mat
So first time snake owner and I needed a thermostat the last one someone recommended to me was for plants but being a noob I didn’t realize that until I started having problems. So traded it in for this. It’s a decent price and I was on a budget. I was worried that it might not work but when I got it plugged in it only took a couple minutes for the heat mat to adjust. The alarm on it is kind of pointless. The thermostat is fairly accurate I have a second thermometer to monitor the temp. It does it’s job, isn’t too pricey and even though people said It’s not a good one it works for me and my snake. So that’s all I can ask. If you want to get on that’s got more settings and stuff then go ahead. But if you have just a heat mat and need to regulate the temperature this will do. I have the terrarium by my window so natural light and temp comes through there during winter it does effect the temp of the terrarium but the thermostat does a pretty good job of adjusting.Great product, decent price, perfect for a heat mat setting.

Great for controlling your pets environment
It works great in my Vivarium and it seems very accurate.When the Remote Temperature sensor with the 6 foot cord is moved to different locations of my Vivarium it instantly reads the different heat levels which is ideal for setting up your animal or plant enclosure to have both warm and cooler areas.The only thing that I Hate about it is that the cord you plug in to control your heating element is plugged in directly in the front which makes the unit kind of bulky.I wish that it instead had a short female end cord that you could place elsewhere to plug in your heating source.I did weeks of researching and I only found one no name brand that had a female cord like I had hoped for. It was also about $10 cheaper but Iâd rather stick with a well known brand when the health of your pet is important.

Mostly good to reportâ¦
I purchased this to control the temperature in my glass/wood tortoise enclosure. Itâs great at maintaining a specific or range of temps. Can manage heat or cool (though Iâve not used cool feature). Â Instructions for use were relatively easy. Itâs connected to a ceramic heat emitter, not light. Â The temp range and current temp are easily displayed. One star revoked for being somewhat complicated to set, but otherwise, itâs a good value for the money! Â

A must for your reptile enclosuresï¼
Have a new baby ball to be set up in a tub with a Zoo Med heat pad underneath it. I know these mats can go up to 120F to 130F -ish and was worried about my animal overheating, and maybe even my tub warping or burning.So far so good, been keeping my temps regulated at 98F to get a temp of around 90 to 91F over the substrate/paper towels. Itâs been running for over 72 hours now with no hitches.You can hear it switch on and off, which for me is reassuring. Itâs not too loud or anything. However the blue backlight I donât think you can switch off, I just keep it covered to keep my room dark as I sleep.Very good product overall! Will probably purchase another one to regulate the âcoolâ or ambient side of the enclosure.

I tried all the cheaper versions made for greenhouses and germination houses and am so glad I decided to spend a little more and get this thermostat for my tortoise terrarium. Instructions are easy to follow and it is very much plug and play – took about 5 min to set up. Keeps the ambient at a perfect 82-85F. The sensor is very accurate – tested many times and it is +/- 1F max. Love the bright digital display and comes with velcro to mount on the outside of the enclosure. It even has a memory after a power outage and goes right back to the temp set. Works with two (2) 150w ceramic heat emitters plugged into a timer that is plugged into the thermostat. Don’t cheap out on the low quality thermostats like Inkbird. This is the one you want for your reptile!

EDIT 4/14/20: Came back and bought a second one of these, because I liked the first one so much! I now have one of these controlling the heat mat for my snake on the ‘cold’ side, and one controlling the ceramic heat lamp on the ‘hot’ side. I will say if there is any downside at all to these, its that you can audibly hear them switching off and on, so randomly throughout the day you’ll hear little clicks as it cuts or gives power to the heat mat/heat lamp. I don’t mind, it lets me know it’s working.Original review: Works well, SUPER easy to set the temperature and it maintains it well. One probe only, so if you needed one for a hot and cold side control you’d be better to get a unit with two probes and controls. But this was a good price for a nice little thermostat that looks very nice and works.

Funciona perfecto y es muy práctico para la regulacion prolongada de temperatura.Te aseguras de que tu terrario este a la temperatura desada en todo momento.

The thermostat is too heavy for the adhesive stickers and velcro. However the actual thermostat itself is great and it does it’s job very well and I trust this product.
