Question: I bought this charger thinking that it would be compatible with my late 2005 iBook G4. The description page has nothing stating that it is not for ibook G4 but only for Powerbook G4 and ibook G3. Also, after only about 3 weeks of use the charger died completely. This is by far the worst charger I have ever had. Pros: quick ship Cons: incorrect description, lack of durability

Answer: Negative

Question: Not only is the heat (btu)rating false, (in my oppinion), but to me it doesnt put out heat at all (relivently speeking) the tip over feature has prevented the unit from opperating several times in the 3 hours since i recieved it.. furthermore.. i will never purchace a heater made of plastic.. think about it.. plastic melts and metal doesnt (at the advertised tempurature) the fan speed i would equate to a gentle breeze if that. the heat output is far, far, below what i would have expected based on the advertisement.. basically in my oppinion this product is worthless to purchase unless you are trying to heat a refrogerator box sized space 5 degrese in a 70 degree enviroment.. look elsewhere for your heating needs.

Answer:
Negative
