I am thoroughly disgusted with the relationship between Costco and Philips and their inability to help a consumer-ME!... bought lightly used 9030's from ebay as I could not afford new ones...great hearing aids I must say...but the rechargeable batteries have been quickly deteriorating and I needed new ones... go to Costco to see if they can help...nope-'you didn't buy them from us-nope'...okay...I'lll go the Philips...will you please ship me batteries?..'nope-you ,just go back to Costco'...they won't help me...then you are SOL essentially...this proprietary relationship is creepy...cant even find what the batteries are...like nuclear launch codes or the Holy Grail...very upset with this...has anybody else had the same problem?
