[Q]: These two short tapes consist of a brief description of 50 years of white-red relations, treaties and conflicts. Because of its brevity, there is little detail presented. The text is interesting and appears to be factually correct. The presentation is relatively unbiased, and is quite interesting. It would make a good audio tape. The extra loud background music and simulated battlefield noise sometimes drowns out the text. The visual portion consists of old photographs, presumably authentic in detail and clips from old grade B movies which are quite far from authentic. These are rerun from 6 to 10 times throughout the presentation and, of course, have no bearing on the text. Except for the extreme brevity and the overwhelming background noise, one can ignore the visual effects and derive a worthwhile understanding of many aspects of the period of the Indian Wars.
[A]: Negative


[Q]: I only used it a couple of times, a tiny bit of water leaked into the battery compartment and now it is rusted and won't turn on.
[A]: Negative


[Q]: Just bought this at the garden center. Looked solid. However, instructions are completely inadequate. I've programmed these kind of things before. I know it's hard to be able to create all the functions needed with just three buttons, but that's why you need to research what the competition is doing.
[A]:
Negative
