i am interesting in buying the rayfoss 30 mw green laser module. i have heard everything from immediate replacement to ignoring about their tech support. i personally think that they have the capability to rapidly respond to questions about a product. whenever i hear of anybody telling that they are interested in buying something they respond quickly but if anybody has a problem with a product and needs refund or replacement, they are ignored. i would like to know if currently, they are holding up to their warranty's or if they are not.
