Serene InnovationsRenew Hearing Aid Dry Box

This hearing aid dryer and refresher works perfectly. I tested the drying effectiveness on the 4 hour cycle by placing two pop bottle caps with a large drop of water about half an inch in diameter in each, one in the dryer and one beside the dryer. At the end of the cycle about half of the water drop outside the dryer remained but the water drop inside the dryer was totally gone.Some reviewers have commented that the battery checker is not accurate. I find that the zinc air batteries briefly recover quite quickly so you must check them immediately upon removing from the hearing aid to get an accurate reading of the battery charge state.

I wear hearing aids and do my best to take good care of them. I've had an old Store & Dry for years and liked it a lot, but it was getting old. It was too large to take on vacation so I had to leave it home, and my hearing aids untreated. Not a good thing.I did a lot of research on the newer style hearing aid dryers and even discussed them with my audiologist. I finally settled on the Serene Renew. I've had it for a couple of months and know it was a good decision. It is small and packs easily into a suit case. The UV lights, which the Store and Dry had too, keep the ear pieces clean and sanitary. The three humidity settings are a real plus. In the Summer, when the humidity in Michigan is high, I can be sure the aids are getting proper drying time on high. For normal humidity the medium setting is fine, and during very dry weather, or in the Winter when the humidity is low, the low setting works.The instructions say to use the UV lights to "freshen" hearing aids from time to time. My audiologist suggested that UV light is excellent for sanitation, does no damage anything, and that I use them every night. I do that. I think it's a smart thing to doThere is a battery tester, but to be very honest, I don't think it is very accurate. I have checked my batteries in the morning and had them go dead that afternoon. My batteries usually last about 15 days, so instead of testing, I just change them. Works for me.Some reviews mentioned the dryer got very hot when on. It does get warm, but according to my audiologist, who also repairs hearing aids, the heat is not nearly enough to do damage. She said not to worry about it... so I don't. It really doesn't get all that hot anyway.This hearing aid dryer is exactly what I was looking for. It takes up very little room on my dresser, does a good job of drying and sanitizing my hearing aids, packs well in a suit case, and even looks nice. What else could you ever ask for?

This dryer does a great job of protecting my hearing aid from the humidity (both use and air!) and I love that it has the UV light to provide some disinfecting as my hearing aid obviously stays in my ear most of the time. It’s silent and good quality. One year in and I havnent had a single issue with it!

I have been wearing hearing aids since my early 30's and now, with it being almost 30 years later, I've been through a number of aids. The drier I used was like many people used - the desiccant device that one periodically heats in an oven. I thought it was about time to try something new, especially now that I am getting new digital aids.I had heard about the electric driers but thought they were kind of pricey from my original audiologist (who just retired). I found the Serene model on Amazon and the features, reviews, and price were right on the mark. I actually received the drier before my new aids were ready. I have had the new aids and this drier for about 1-1/2 weeks so I don't have a great deal of experience with either. I will say it is very easy to use, appears to be a solid, well-built device, and operates as designed.There are a couple of features which are nice but I probably will never use them. That is, there is a battery magnet to hold the batteries should you wish to remove these from your aids while they are in the drier. I see no point in this as opening the battery case is what is needed to turn off my aids. Perhaps, some other aids need this. The other feature is the battery tester. Aside from not having the aids work being a pretty good indicator a battery change is needed, my aids actually talk to me and tell me I have a "low battery." So, I don't see much use for that feature, either.I checked with my new audiologist and mentioned that I purchased the Serene drier. She gave it high marks and told me they sell the same unit at her practice (although she did not mention the price). I think that's a pretty good recommendation.Now, I will say for traveling, I do keep the standard desiccant container available. At home, I use the drier and UV light on a nightly basis. I would suggest cleaning the aids before putting them in the unit. In that way, they are ready to go the next morning and also would be completely dry from any aid cleaning cloth you might use.In a nutshell, I like the unit and I believe it will help keep my new aids working longer. I'm very pleased with the unit and its performance.

Works great !!!Disinfects ,dehumidifies , keeps batteries secured and tests them for you !!! Good deal, worth it .
