Your satisfaction is guaranteed with any item you buy from Lightglass Optics. If the item does not meet your needs, please send it back within 10 days for a replacement or refund of the full purchase price. Our hours are 9 to 5 Mountain Standard time Monday through Friday. Being a web-based company, we do not have a receptionist. We are out shipping or getting inventory much of the day, so email is a much better way to contact us. Phone calls may be futile..
