If you are thinking of purchasing a Perfectdry Lux, I suggest buying it from Costco.
Reading lots of the reviews for this product on Amazon, it appears that there are a number of early failures, with purchasers being stuck with a defective product and no clear way to use the manufacturer’s three year warranty.
I visited my local Costco where I bought a Perfectdry Lux for $39.95, which is half of what most other outlets are charging. The person who waited on me said that because I was not a hearing aid customer, and not in their system, I should make sure to keep a copy the sales receipt in case the unit failed within the 3 year warranty period. If I presented it to a Costco audiology department along with the defective dryer, they would handle the warranty.
Needless to say, I immediately scanned the sales receipt to a pdf file when I got home. If the dryer makes it through 3 years, it will probably last forever, and from what I have read it’s usually a fan failure. These are tiny multi-blade computer fans which are cheap as dirt, and should be easy to install.
Now regarding the drying time. All the specifications and advertising I read online state it runs for 30 minutes, with many folks saying it’s not long enough. Interestingly the documentation in the unit I just purchased (09/23/2020) says the drying time is 45 minutes. I plugged it in and It did run for 45 minutes. I’m guessing the manufacturer has been reading the online reviews, and made a running change.
How well does it work? I have no idea, because the humidity here has been low recently. Even though I clean my aids every evening with alcohol wipes, I do like the idea of exposing the tubes and domes to UV light to protect against germs.
