We bought two of these.This product. Does not fit 128 disk. The folders are so tight against the edge once you start filling it. It becomes impossible to out disk in towards the back of the case. Will be looking for somwthing decent.

Ex Output:
negative


Ex Input:
Buying these is like playing Russian roulette. If you get a good one, like a friend of mine's, they are well worth the price. But the one I received had parts that did not lock together and the rotor wobbled. I returned it.

Ex Output:
negative


Ex Input:
Bought this product almost exactly one year ago. Worked great. Changed the batteries about 4 months ago. Changed the batteries three times yesterday and the door is still saying the batteries need changing. This morning I checked to see if my cats were locked out in the cold all night. Thank god it still works, for now.

Ex Output:

negative
