REPTIZOO Dimming Thermostat, PID Temperature Controller with Memory Function, Reptile Thermostat for Reptile Heat lamp, Specifically Designed for Light Heat Bulbs & Heaters

So I've only had this for a couple hours. Ones I've tried in the past didn't seem to work right. However. This one seems to be working great. It's definitely off a few degrees. It's set at 82° f, thermometer that I have in there says it's 85° f, but the temp gum reads between 85° f to 90° f. Which actually worms greatly for her. I did notice the light finally dimmed. It was at 82° for over an hour before it dimmed. I noticed my other thermastats different brands ( bn link, two different kinds from bn link ) were actually not dimming them but turning the heating element off which could potentially cause more issues in the long run stressing the equipment turning off cooling down then turning back on re heating multiple times through the day where this one dims down to keep and maintain the temperature instead of rapidly changing through out the day. So far I'm happy with it. Will do an update in a few months If there's any changes. Shipping was on time. Nothing damaged from what I can see. Overall happy with purchase. Maybe I'll be able to relax a little more now. I'm constantly checking her Temps due to issues with other products.

Works as it should, is accurate, and the price isn’t bad. Would buy again.

This thermostat has served me well for over a year (knocks on wood, buys a backup in case). My leopard gecko has been comfy and warm through 1 whole Wisconsin winter.

Once this is running and the conditions stabilize, the dimming feature functions pretty well to maintain the temperature within 1-2°F of the set temp, however, when compared to another thermometer with accuracy I trust, I found the temperature calibration on this is off by about 10 degrees (this unit measures 85-86°F while my trusted thermometer is reading 95-97°F). There is no way to fix the calibration on this, so it must always be used in conjunction with an accurate thermometer to ensure it is producing the desired temperature. For the price, this isn't bad, but I wouldn't trust it completely on its own. It's very simple to operate, displays clearly, and it's efficient. Does what it's supposed to do.

Works well. I've bought 2 now and will buy again if I ever need an additional one.

Product review on the ReptiZoo PID Mini thermostat. Absolutely love these! We use DHP day and night. Day temp set to 87° and night temp 81°. It gradually heats the enclosure, which seems more natural to me instead of 81°, BOOM, 10 mins later 87°. It's 5:30am in Central Florida and I just set the 2 thermostats to 87° for the day. The ambient temperature will reach 87° around 10am and be maintained throughout the day. The thermostats do allow a 5° temperature variation DOWN, but when I check my Govee's there is not major fluctuation, maybe a degree or less. See pics. Don't mind the temps looking off, I have my Govee's in odd spots right now so they look low but they're more on the cool side right now, but you can see in the graphs they are no more than a 1°F temperature drop at any point. We tried Pymeter dimming thermostats and loved them, but they emit a high tone that drove my dog nuts. Then we tried Inkbird, but they were on/off, and even though we had it to turn off at only 0.5° below the set temperature, the temperature fluctuation was ridiculous. It would often get 6-8° below and up to 4° higher than our set temp. Then we tried CavaChew and they were ehhhh. They allow that same 5° temperature fluctuation as the ReptiZoo but they really had fluctuations that I was able to measure with our Govee's, so ambient temp fluctuated a lot. We have our probes dangling beneath the DHP to get accurate heating temps (took some playing around with for correct basking temperatures), but after a day or 2 we got it. They are inexpensive, super easy to use and set up. Both our BP noodles now come out to bask or explore nightly as soon as the lights turn off and don't go back to their hides til the sun comes up. We do routinely measure the basking areas to ensure they aren't too hot, and never exceed 93° at night. They hide all day, so basking temps are a bit higher during the day, but they never come out during the day. We were previously using CHE for daytime and DHP for night, but switched solely to DHP 24/7 and it's worked wonders. Temps are on point, humidity is on point (higher right now for shedding), and not over drying our substrate. We're only having to add water once a week and mix the substrate every 4 days. Overall, love these thermostats and highly recommend them. We will be switching to PVC 4x2x2 by the end of the year and using radiant heat panels, so I'm going to have to research how these thermostats work with those as far as probe placement and accuracy. Excited to see what's to come.

Update 12-10-23 I received a new thermostat and it works! The first one I received must’ve been a one off problem. It keeps the ceramic heat emitter within a degree of the 75 degrees Fahrenheit that I have the thermostat set at. I bought this thermostat to control a 25 watt ceramic heat emitter for my crested gecko. At first it stayed with a couple degrees of where I set it. It hasn’t worked that well since. As long as it was staying within 3-4 degrees I was working with it but when I had it set to 73 and it was up to 81 (a couple days after I set it up), that’s it. I work full time and can’t trust it not to cook my gecko. I reached out to ReptiZoo five days ago and have yet to hear back. I’m returning this one and have purchased another one to give it a second chance. I’ll try to remember to update my review after I get the second one set up. 🤞🏼
