Mar 18,2025Very good product, not expensive and like the description. The datsheets should be more detailled but it is ok.

Mar 05,2025Excellent customer service. My order was delayed due to weather and after I noted I had not received my order, customer service reached out to me. They had investigated the issue and reshipped my order the same day. Days later I not only received my replacement order, but the original order showed up as well. Plus, they followed up to make sure I had received my order. I will definitely use Optcore again.
