  1. David Dick

    I put my E-333 model into use over two years ago in November of 2017, and I must say I’ve been pleased at how it keeps the air in my gun safe nice and dry. During the humid summer months I need to recharge the unit about once a month and is very easy to do. But in the less humid months of winter I need to recharge only every other month. This is a fine product for small places, such as a cabinet or safe, and I am very pleased with it. And in case it matters, my E-333 is of the older style, where the hook is shaped differently (an “open hook”) as well as being removable.

    I originally found these at Costco 2 1/2 yrs ago. I bought two 2-packs calculating that was how many needed for the 10’x20′ cargo container I had my household stored in. The four units would last 4 weeks and would need to recharge. They worked much better than those messy crystals in the buckets that you had to pour down the toilet to get rid of. The Eva-Dry E-333 were reliable and so clean. Within the last year I upgraded to the E-500’s to give me more peace of mind that over last winter I wouldn’t have any mold and mildew issues. I also had something to swap out with during recharge periods. I recently was able to purchase a new home and move everything out of the container. Happy to say I did not have any mold or mildew issues, and the wood furniture was not warped or damaged. I am now going to use these in my garage and upstairs inside my home to make sure over the winter I don’t start anything nasty. These are a great product.

    I have over a dozen of these, mostly of the previous design. I loved the previous ones and use them all over my house, RVs, and vehicles. The last ones purchased were of this new, current design. I thought that I would like it too but have been very disappointed. The hook is the issue. It can’t be removed but it does break off with that small lid part that it is attached too and then your have the tiny beads from inside all over the floor. I collected what I could of the beads and then taped over the missing cover and hook, since those can not be put back in. It took just a tiny bump into unit for the hook area to break off. So be very careful if you hang this unit up. So disappointed and will not order any more until the current design is changed.

    I use this dehumidifier in my gun safe and it works great. As others have said, it’s so easy to recharge, since you just plug it in for a few hours. It’s worth every penny I paid for it.

  5. Ronnie

    Product works good. No issues

  6. joseph strupek

    Works great have two in my gun safes and bought one for my grandson for his gun safe. Easy to recharge

  7. C. McIntyre

    I have 2-3 of these.

    They work great. I keep one in my gun safe and then one in a room that gets a little musty.

    I like how to recharge, you just plug them in for 8-12 hours. That is far easier to me than the metal cased units that you need to put in the oven.

    Overall, as my safe and gun selection increases, I’ll continue to add these. I’m strongly considering getting one of these for each of my ammo cans-if they made a half size model, I’d definitely have one in each ammo can.

  8. DCR

    Bought this for use inside a safe, so far so good.

  9. AuroraBorealis

    Keeps my car dry and fresh, which is very important living in the rainy Pacific Northwest. Refresh time is quick – all you need is an outlet. Filled up faster than I expected (became saturated a few weeks after putting it in my vehicle) but when it only takes a few hours to refresh that’s not such a big deal.

  10. Dan Cochran

    Works Very Well to help my Filament Dry in my container,, Over time it will even help Brittle PLA become more Dry over time.
    One Day I plan on a few more.

  11. Derfman

    So far so good. Bought this for a large gun safe I purchased to store guns, pictures, and other valuables. Working well so far! Basement is quite dry overall, and this is lasting a long time. Time will tell, but is working well so far.

  12. V

    so easy to have and use. recharging is relatively quick as well

  13. Amazon Scott

    I use this in my Sentry fire resistant safe that I use to store back-up hard drives. There are a lot of reviews for fireproof safes regarding moisture problems, so the mini dehumidifier fit the bill. All you do is plug in the unit for several hours until the beads change color – it heats up inside and dries out the beads. I have to plug this in about every 4-5 months to reset the unit so it will absorb humidity again.

  14. R.E.M.

    I have this a month or two and it seems to do what as advertised.

  15. Are Em

    Works great in our 3D printer

  16. Lindsay Pando-Bare

    So far so good, I did a grow with this before it needed to get recharged and yes it does get hot so do keep an eye on it.

  17. Natus

    Works great so far. Seemed to do its job because I had to recharge it in about a week.

  18. jggmc06

  19. Patrick Thompson

  21. Cameron Graham

    Keeping 52 gun gun safe at 36% humidity all winter Good bang for the buck

  22. Handyman

    I bought this for my gun safe. Seems to work very well. I really like the fact that it can be used over and over.

  23. Amazon Customer

    WORKED VERY WELL, AND THE PRICE IS GREAT!

  24. Madeline Audrey

    I use this little dehumidifier in my tiny bathroom. Even though I have a fan in the bathroom it still would get mildew spots from the steam. I’ve had this in the bathroom for a couple months now and I haven’t noticed any new mildew spots. I have to plug it in every week or two since there is so much moisture in the bathroom, but that is a very easy process. I love the size and ease of use!
