- *****- Feedback left by buyer.Past yearVerified purchaseGreat company to work with. Superb communications and resolutions. I bought the Portable Optical Glass Polariscope and began using it right away. It worked great - until - the flashlight (torch) bulb burned out after just a few days use. I looked online to find a replacement bulb but couldn't find one. I contacted discount_instruments about the problem and they sent me a replacement flashlight (torch) right away. This is the kind of company that I like doing business with. 5 Star
