Good product for a great price.

I still haven’t received my order. UPDATE I RECEIVED MY PURCHASE

I can’t write a review or give an accurate start rating because my order never arrived. I tracked it through FedEx and it showed that it never left the seller. I contacted Olympus Myco for information regarding my purchase or a refund, they responded almost immediately and assured me that my purchase is on the way. I can’t review the product but I’ll give them 3 stars for answering my email so quickly and professionally. Although the above is true my product did arrive a couple days later and I’m very satisfied with my purchase.
