I saw an ad for them, but know nothing about them.
I was dealing with Collins cartridge Company, out of texas, Got an invoice, and email saying my shipment would be delayed. That was Oct 31. Emailed them middle of Nov, and first of Dec. No product, no response, web site says what I ordered is now in stock. But the price is up.
I was not billed on CC, for the product. But very poor response to inquiries.
