This is the worst company to deal with! I bought the Ergoprism, took 2 1/2 months to receive. Not the problem though. My loupes came broken, and even the name plate on the case fell off in a day. I have called emailed, left VM’s, more than 10 times, to speak with anyone about the broken loupes. Took 9 days for someone to email me. Which they said “I have enclosed shipping label and we can re-glue the broken piece”. The shipping was through USPS. SNAIL MAIL!!!! And just “glue” the broken piece. No sorry, no nothing! So they expect me to send my loupes back wait for the mail carrier, they glue, then wait for the mail carrier. This could take a month or longer. Called, emailed 10X more times stating I am leaving the country and can not have a package this expensive left on my doorstep. I am beyond words with how unprofessional this company is. I just want my money back now. Because of this is how I will be treated with any future issues, forget it!!!
