Pioneer Silent Dry Cordless Gun Safe Dehumidifier – Reusable Mini Dryer for up to 20L – 9 Min Fast Rechargeable & Moisture Removal for Guns, Safes, Cabinets, Cameras – Swat Black (1 Pack)

I’ve put this in my car a week ago and haven’t had any issues with foggy windows since. Still going strong, even with the space being much larger than recommended (20L). Admittedly my car is on the smaller side (Audi TT), so I’ll update how long it lasts until it needs “renewing” (by placing in oven or microwave at specified temperature and duration). This simple process causes it to shed the accumulated moisture so it can be reused multiple times. Quality product!

I use these in my gun safes, tool boxes and displays. Fast recovery less than 10 mins to reset. Great as a back up as well. I have electronic versions that take up to 4 hours to reset.

Good

The media could not be loaded. This great item make me want to write review and upload unboxing video for the first time!!!! First time saw this kind of dehumidifier, was order with doubt though. Indicator showed blue while received it, so I put it into microwave to renew it as instructions said. After putting frame back, the indicator turns to white in hours. It works well to my gun case, humidity decreased. Gonna share it with my friends. Good Job!

This is the second time to purchase this Dehumidifier. Works great and easy to use!

I've had this unit for 4 months. I have dried it out twice before now in the microwave. This time however, it burst into flames after about 6 minutes. Luckily, I noticed smoke rising in my kitchen and saw it burning and was able to remove the turntable plate with the fire on it and take it outside quickly enough. However, it torched the upper part of my microwave and dripped plastic down below, making it unusable. Use extreme caution and consider a very low power level of you're going to buy this at all. My vote is just simply don't buy it.

If you have a safe and guns in that safe you must protect them.

Seems to work OK
