Vivitar S-100 Rotary Slide Tray

The slide tray I ordered was just as advertised, worked great. My Kudos to the seller.

I don't have any experience with other slide projectors with which to compare quality, ease of use or reliability. The slides in the Rotary tray are - by design - difficult to locate to edit. I have had no difficulty operating with the Rotary Trays except when a slide has previously been damaged.

I have 24 of these slide trays, all filled with 35mm slides. I have not had any problem with them at all. They run through my Vivitar slide projector just fine - after all, they're made by Vivitar, so why not? I do have three other trays (gray, instead of Vivitar black) that appear to be made of a bit heavier grade of material. However, I don't know who made them. If the Vivitar trays are compared to them, I guess it could be said that the Vivitar trays aren't made as well. But, the difference(if any)is slight, indeed. I see absolutely NO difference in performance between the two types of trays when I intermix them during slide shows. I will not hesitate to purchase more Vivitar trays as future needs dictate.

I recently received six of these trays after not having bought them for quite a while. The quality of the new trays was very poor. Whoever makes these has a serious problem with their molding machine, but the resulting flaws should have been captured in a quality check. I'm ready to dump this system and go with Kodak.
