Query: IT BLEW UP !!! But all is good now.

Used product for the first time today 8-17-08 and when it reached 10 lbs the pressure guage blew off. It seems there was a problem in the casting of the metal. Made sure when I installed it not to tighten too much. Also read in another review this happoning to someone else. I am going to call Presto tomorrow and raise he.l. Buyer beware to be carefull when using this pressure cooker. (Update) 11-11-2011 Called company and they sent new gauge. Have had for a few years now and it works great.
