What can I say, turns on and heats up as it is suppose to do. Hot to the touch but not burning.

Has clear instruction to dis-assemble and re-assemble if needed. I did not have to, because I have outlets inside my safe.

Has kept my 19 cubic ft safe (in dry basement) at 55% humidity at 67 degrees since running 24/7. First day of install, safe was at 71% @ 65 degrees but the weather and basement has gotten colder, while safe has stay consistent.

I've seen reviews on how well this device works, but it had absolutely no effect on my safe by itself. The final combo that I found to regulate temperature and humidity is a golden rod, evadry 500, and a USB desk fan. I place the goldenrod on the bottom of the safe, the Evadry in the middle, and have the fan blow air past the Eva dry. The fan does an amazing job to circulate the heat as well. My safe is a 40 gun that is stored in my garage that is insulated but gets pretty cold. The combo brought the temp in my safe up to 58F and 49% humidity. Before I was not able to get it below 60% with the rod and evadry. The fan is the real trick here.

One of many devices I use to keep my refrigerator size gun safe outside in a non heated garage. If you're interested in what I did, here is my rundown.

Cold weather storage...
1. 24" goldenrod on the bottom floor of safe.
2. One Peet Dryer (small one) - second shelf.
3. Some of those rechargeable - moisture grabbing crystals. $12

My safe has 3 ac and 2 USB ports for power....
My Safe maintains a steady 66f with 45 humidity level. This is maintained when outside temperatures are 25 to 40.
I have yet to experience what happens when the temperature drops to zero, but my garage will still be in the 20's. I'm confident the safe temperature will stay between 55 - 65.

I only need the dehumidifier crystals in the summer for some reason. Now that it's cold the crystals stay blue. In the summer they go pink an 5 days.

For those of you wondering about garage or basement storage, that's my experience.

Excellent Dehumidifier for Large Safes!!! The 36-inch model is quite long so make sure you are a large safe. I also found their "mounting" brackets - just a couple cheap plastic holders to be useless but I couldn't mount the unit on my safe floor anyways because it got in the way of the door / contents. The solultion? I have this unit hanging vertically on the inside right corner. It fits perfectly there and is easily supported by some ammo (or anything else that weighs about 5 pounds+) on the upper shelves of the safe. Before buying a 70 pint / day Dehumidifier, the unfinished basement room where my safe is located was running about 60-70% humidity during the summer and the inside of the safe was near 50% even with various rechargable units and packets. Now humidity in the safe runs steadily near 20% and never exceeds 30%. It's true that all this unit does is procude enough heat to thwart moisture, but apparently that's all it takes!! Regarding the "heat," I just make sure the rod is free standing and not touching anything. It's not going to burn your arm off but you wouldn't want to to grab it with both hands either. As long as its not directly touching your valuables or the interior of a non-metal safe you are good to go. So happy I bought this, you will be too!!!

PS for those interested, the dehumidifier I bought from Amazon is the "hOmeLabs 9 Gallon (70 Pint) Dehumidifier Energy Star Safe Mid Size Portable Dehumidifiers for Basements Large Rooms up to 4000 Sq Ft with Fan Wheels and Drain Hose Outlet to Remove Odor and Allergens" - I LOVE IT!!! Had a plumber hook it up for continuous running with no emptying buckets - unit works great!

Not sure where there's so much drama in some of the reviews. The one I got says, "Made in America" and does the job. Essentially what you're buying is a very small space heater to warm the air in your safe and thus dry the air. I also purchased a digital hygrometer to measure air temp and humidity.

Ensure you get the length right. You probably want the biggest one your safe can hold. Also, it's AC powered so your safe must have a hole for an AC line.
