Real feedback from verified buyers
Very easy to navigate on the website, I found what I wanted, and after a few days the device arrived and it was exactly what I needed.
There is a wide range of products available and I am very satisfied with the quality of the product.
Fast shipping, reliable products, great customer service, I had a few doubts about the device that I bought for my parents and I had the total customer support.
As someone that spent probably too much time in clubs in my younger days, my hearing is especially important given the minor issues I'm already experiencing. Hearforless had me covered. Great fast advice, and a great product which has served me well ever since when I've needed (or wanted) to be in noisy environments and look after my hearing. End result is that I can still enjoy things like concerts and hear great sound, without over-taxing already damaged ears.
I use Hear for Less for work from time to time, staff are so knowledgeable and so helpful. They would climb a mountain for you. Would recommend to anyone for professional or private business. Customer service is great, communication is awesome, pricing is in line with competitors, delivery is seamless, items arrive at clients doors quickly, a lot of happy customers! Thanks team for the great work 👍
Unbelievable service, ordered hearing aid batteries at 9:00 in the morning & they were delivered in under an hour to my door. During times of lockdown & COVID that was totally unexpected & much appreciated. They were also much cheaper than what I usually pay. Highly recommend them for outstanding customer service
