    Shipping, packaging (WELL packaged BTW, the way IC devices should be packaged), as described and VALUE......ALL GOOD. Great Ebay seller here. I know that they regulator IC's work well, because I accidently blew one up and had to use a second for replacement. So, IC's were good here as well. Thanks for the positive buy on this. Would buy from this seller again. :-)
