Hi there I have 2 sets for sale, are in excellent working order. Keeler Retinoscope and Opthalmoscope W/ 3.5V charger and converter so you can use with C-Cell batteries. Heine Retinoscope and Ophthalmoscope 2.5v with C-cell batteries. Both come with student cases so everything fits and can be transported. These sell for over $1000 new and I am looking to get $600 each. They are this year or last years model and are clean both physically and optically. Cheers!
