We have had wonderful experiences with both Jay and his staff. Some of them are better than others, but they have taken very good care of us. You can look at my other reviews and you will notice that I wrote a scathing review of Lauren Diamonds and Gary Casey. When I no longer entrusted Gary with my money I went to Feders (not online, as he states) and we have done very well there. I warned them up front that we are tough people to please and that we would take our business elsewhere if it was necessary. However, they came highly recommended and have a long-term reputation as one of the best places in Denver. The prices are stellar for what you get in service and support. Hope this helps.
Pros: Service, support for product, straight forward advice, free and Kosher food:)
Cons: Closed for some religious holidays, but can make appointments
