Absolutely terrible service. I have been trying to get Ergoprism loupes for two months. I paid more than a month ago. The response time for telephone calls/messages and emails has been 10-14 days, causing repeated delay, only to have the photos I submitted called "great!" but not good enough - they all need retaken. I followed their instructions precisely, for example, wearing the frames they sent in the fit kit for all the photos. Yet their only details on what to do differently were "you did not wear the frames sent in the fit kit for the photos" and "use higher resolution" (than the highest resolution on my Samsung phone? What resolution then?). I asked for details so I could make the proper changes, but have never received any response. They still have my $2533.00 but are completely unresponsive and are not delivering anything, let alone the Ergoprism loupes I paid for. I really love the concept of the Ergoprism and want such a loupe, but this company cannot/will not deliver that concept, at least to me. Do NOT work with this company if you value your time, responsive customer service or a quality partner in your business. You are left completely on your own. The frustration factor is immense.
