I found the service and technology at Costco to be excellent. One of mine went dead after nearly 2 years. Took it to the Costco in Puerto Vallarta and they fixed it free, without a word of English being spoken. I was impressed. So I got a new set from Costco for $1600 that has bluetooth and a phone answering button and an app for fine adjustments. Audiologists were quoting 4 to 6 thou and the testing and equipment was sub par. Now if I could find a place that will make prescription polarized sunglasses without all the markup....
