Purchased the first pair and experienced a failure in 5 weeks. I was assigned an Eargo contact that arranged for a replacement and for the bad Eargo be returned. I was informed I did not "maintain" and clean my Eargos. I had a second failure and had difficulty contacting someone. Eargo did honor the warranty and replace the unit. At failure #3 I submitted a complaint to the FDA and state consumer advocates. At failure #5 I was contacted by Eargo legal and offered a full refund in exchange of rescinding my state complaint. The Eargo fits great and performed as promised. But the design doesn't keep debris out of it. User's recommendation: There are other options. Research before settling.
