Products that promote the use of IAC2 inspectors dominated the Vegas Hardware Store Convention.

Every vendor catalogue at the show had sleeve that advertised retail products that promote the use of IAC2 inspectors.  There were over 3,200 vendors at the May 6-8, 2008 show in Vegas and IAC2 was everywhere.  IAC2 inspectors are recommended in over 50,000 retail outlets across N. America: https://www.nachi.org/50000retailoutlets.htm
