Yes their repair and customer service is top notch. I also had a crack "suddenly appear" in my left A12, they fixed it in a few days and I had them back in a few more. Crack was gone, they filled it in and even upgraded my modules to metal from the plastic kickstarter ones. I'm very impressed and If I order any more CIEMs they'll definitely be from 64, knowing that they have my back if something goes wrong. I see a lot of people order from companies in other countries and shipping their impressions overseas, as often as issues occur with ciem's I'd hate to be shipping things in and outside of the country dealing with all the crap you have to deal with from the government to ship things internationally(VAT's, inspections, etc) and possibly things being lost. I have nothing against things made overseas-I'm all for it, just not something I want to do with CIEMs. Customer service is a MASSIVE part of my purchasing decisions.
