Update: (I had one hearing device fail, but not completely the sound was just scratchy and I thought BLJ only had a 30 day warranty. I was wrong on that point. The warranty is for one year and once BLJ made that clear to me they took care of the problem. I am now returning my rating to 5 stars. I've been using these now for about 7 months and they are very durable and are very easy to use.) These are great little devices. Well here is the deal with these hearing aids. First they are very small, don't be fooled by the pictures. It will take some time to figure them out. You will have to figure what cushion fits you best. They come with, small, medium and large. I tried them all. I found that the small work best for me. There will be a lot of squeal while you try to figure out what volume, mode and cushion to use. Also you will have to figure out how far to push them into the ear canal. I was getting squealing if I put my jaw in a different position and I found this very annoying. We are made of flesh and bone and when we move our mouth it will change the shape of the ear canal. I found that this problem can be over come by placing the hearing aid deep enough into the ear canal to assure a good seal to prevent feed back (squeal). Don't give up on these little hearing aids, for the money they are great. I'm hearing, birds, crickets, and frogs. These are things that I didn't even realize were missing from my life. I can keep up with conversations much better now. You will have to give your brain time to adjust to the new sound and it will start to seem more normal as time goes on. I tried Eargo and I think they are the best out here on the internet and the people that make them will actually talk to you and provide the best help and service. The only problem is my hearing lose is so bad that Eargo could not provide the volume that I needed. So I returned for a full refund less handling cost. I am !00 percent satisfied with the BLJ hearing aids. I have the left and right. They provide great volume and with 3 modes you have a very good chance to find one that works for you. The price is fantastic! I've only been wearing these for a month, so I think I will continue to figure out more ways to make them work better for me. I prefer the battery rather than charging types. With batteries if they go dead while out and about, no problem just put in a fresh battery and off you go. I keep a pack of batteries in my billfold, that's just too handy. All I can tell you is no matter what hearing aids you try you will have to do a lot of experimenting to get them right. So hell, I've done all the work for you with this brand. so get a pair of these and use my advise and start enjoying telling other people to not talk so loud. Good Luck my friends.

I have purchased many hearing amplifiers and spent much more than I can afford but none seems to last and some just don't work. I have trouble getting the devices into my ears.. I guess I have small openings. This pair is small enough to fit nicely and is invisible to the eye. it also has a button volume control which works much better than the ones that require a screw driver. it's sound is good. I'm still trying to adjust the volumes and modes but will get them better with time. I am so happy to find one that fits and actually works. The price is less than many others that did not work. It gets my thumbs up!

I'm updating my initial review. Although I had issues with my device I did and still do acknowledge the product works great!! Linda's excellent customer service to resolve my issue is refreshing. She contacted me right away and shipped new devices to replace the two I had issues with.

I would definitely recommend this product, I struggled to hear and it's such a relief to be able to fully hear again.
Thank you BLJ and a huge thanks to Linda!!

I bought it for my husband he likes it better than anything else I've ever bought him for his hearing but it's really hard to get the volume right

Worked great and then it stopped working for no reason. Very disappointed in that the seller states in their product description there is a one year warranty, but there is no way to contact the seller. I did contact Amazon customer service and they were great in that they issued a partial refund. I guess something is better than nothing. Just wish I could have spoke with the seller and got a replacement.

Update: Great news!!! BLJ contacted me and apologized for the issued I incurred. They sent a NEW replacement for both ears at no charge. As I said the amplifiers work great and I even forget I have them in until I lay down and they squeal. I have tried other amplifiers and they would continually click off and on or squeal constantly, since wearing the BLJ amplifiers I haven't encounter any problems whatsoever. Thanks John John
