I purchased this hoping to keep the excessive moisture buildup in my safe under control and couldn't be happier!About a year ago I purchased a First Alert fire proof/waterproof safe, which has an airtight seal. After I got it and read the instruction manual I found out that they state that the fireproofing materials used in the safe cause excessive moisture to build up inside the safe and suggest opening the safe on a regular basis and leaving it open to allow it to air out. This is obviously (at least for me) not practical since I got the safe to keep money and other valuables safe.I shrugged off their warning about opening it and placed my items inside and rarely opened it. I found out after several months that my money and other paperwork was very damp and smelled like mildew. So, then I started opening the safe more frequently, which did not help at all,, considering I live in Georgia where the humidity is already very high (so opening the safe just exposes it to similarly damp air.)The moisture was so bad inside the safe that liquid would actually pool on the bottom after being closed for extended periods of time.I then tried placing items inside ziplock bags, which did not work. Then purchased dry bags designed for keeping items dry when boating, etc, and even tried glass storage containers with ridgid plastic lids with gasket seals to place items in (this is what the manufacturer recommends). The dry bags didn't work and moisture still managed to work its way in. The storage containers worked better, but not perfectly.Then I purchased this Eva-dry E-333, which is the small one. I figured I didn't have that much to lose, considering that it doesn't cost very much. Well, I wish this had been my first purchase as this item works!The day I recieved it, I opened the safe and noted that there again was some liquid accumulated on the bottom. I placed the Eve-dry inside, along with the packing slip that came with it (to see how the piece of paper did being left inside the safe). I checked back the next day around the same time and all the moisture on the bottom was gone and paper was still crisp and dry. I then left it closed for several weeks and then checked again. This time I noted that the crystals had started to change colors (they were purple-ish-pink) and safe was still dry and paper still crisp and dry also.I then removed the Eva-dry and plugged it in to refresh it. The next morning the crystals were all blue again and I returned it to the safe.I had no problems with the plug or it falling out of the outlets. I does have a good bit of weight to it compared to a normal cord or power supply; however, if your outlets are good you shouldn't have any trouble. I had all of mine replaced about 8 years ago because many of the old outlets would not hold plugs well in general. If you have outlets like that, this thing will never stay connected, but not really a fault of the product. Using a power strip would also work fine, if needed.Bottom line - It works for my needs (small, enclosed space), you don't have to buy refills, and it's very affordable. I wouldn't recommend this to dehumidify a room, closet, etc, as I seriously doubt it would be that effective under those conditions. The reason I say that is that I've used regular electric dehumidifiers before, which are capable of removing a couple gallons of water every few days and although they make a difference in overal comfort, even those don't do much to lower the actual relative humidity reading within the space.

I’m honestly quite impressed with this little product. The apartment we live in has a small master bath with absolutely no windows. As often as I clean the bathroom fan - that alone hasn’t been enough to deal with all the extra moisture in there. our toilet constantly sweats all day long, dripping water on the floor, it’s quite annoying.We only have one outlet plug and that is right by the sink with no counter space for a traditional dehumidifier. So I took a chance on this little machine. It sits right on top of my bathroom cabinet, it doesn’t need to be plugged in while in use. There are silica beads inside that collect the moisture. When the orange beads turn green- you then plug it in for 12 hours while it dries out the beads. There are no indicator lights and it takes no effort to use. I was able to go 3.5 weeks before having to plug it in and recharge it. It’s done wonders for the humidity in my bathroom- I judge that by the fact my toilet no longer sweats all day long!

Alright, let me begin by stating I live in south Louisiana where humidity is a major problem. I keep 2 of these in my safe, and they keep the levels around 48%, which is around 10% lower than my household humidity level. They do however have a shelf life, and will last about a year with heavy use.They will need to be recharged frequently, as I have to charge mine once a week, because the beads become totally saturated. Be careful! The unit will become extremely hot to the touch when rechargingEva-Dry has exceeded my expectations after having used unsatisfactory humidifiers in the past. Its rapid, effective, and energy-efficient design has been a welcome change, as it quickly removes excess moisture from the air with no leaks, spills, or unpleasant odors. I've had no issues with its performance, and I can even see the moisture being extracted from the beads while it's plugged in.Buyers should be aware of imitation versions of this product, because I have tried several, and they do not perform as expected. This company is great to deal with, and honors its genuine products and guarantees 100% customer satisfaction.I only took away 1 star because of the frequency needed to recharge, but keep in mind, as stated, I live in a very humid environment. I will purchase more in the future.

I am so pleasantly surprised that these actually work for a small area!! I measured the humidity level with a thermometer that also reads the humidity levels. It kept the humidity low! And yesterday I noticed the humidity was higher than normal so I saw that I needed to plug them in for the first time in over a month. Overnight it cleared the moister/water out of these devices!! This is crazy. So happy. First photo was last night and the second photo was this morning all dry and new again.

Seem to work well. When the beads turn bluish green you plug it in & it heats up & dries the beads out. When they are orange again, it’s ready to use again. Dries out while plugged in overnight.

Best Dehumidifier I've used in my refrigerator so far. I purchased very large dessicant packs and they did not work and they broke. Searched for an alternative and found this. My humidity was at 95%, and is now 75% 4 hours later. I purchased 2 so that I can keep a good rotation going while the other is plugged in to charge.

Bought 2 about a month ago for moisture issues in small guest bedroom & office closets. These has been no moisture since in either closet. The color does change from orange to green when needs recharge & so easy to just plug in. Set a reminder on my phone so I wouldn't forget & was orange again in about 10 hours. So happy with results, I'm back to buy one for my car.

Me encantó este producto, ha ayudado mucho a mantener la humedad a raya en un closet con poca ventilación. A los pocos meses se tornó a verde, lo cual indica humedad, lo conecté y volvió a naranja. Lo volvería a comprar

Good performance

Cost effective- no need to buy refills for the disposable dehumidifiersCordless - perfect for the bathroomQuick dry - the gels dry within 4 hours of plugging into the mainWorked in every room.The bathroom was my biggest headache and I assumed we willneed two of these cubes, but one was sufficient. Colour changing is accurate.I now have one in every room. You’ll need a UK plug converter but apart from that, it's worth every penny. I tried every other brand but non worked like the Eva dry.I wished I had discovered this sooner. I would have saved myself a fortune.Brilliant 👏 quality

Works, but don’t leave drying too much.
