I finally had the opportunity to see how great they we're. The little cam piece broke on the sprue cutter. Six cavity mold. Sent them an email, got a response the next day. The rep asked me to attach a photo to the email or mail the broken part in. I took a pic. Sent it. Next day I got another email, part is in the mail. Got it 3 days later. So , yep everything I heard was true.
