Midway is able to offer you this product at a great value because it has been lightly used or tested. It may have minor blemishes from previous use, but still holds the same quality and warranty that is Swarovski. The 20-60x variable eyepiece by Swarovski provides bright, crystal clear images right up to the image periphery over a wide range of magnification. Eyepieces are compatible with spotting scopes in the ATS/STS range and can be quietly and easily changed at any time.
