[...product B which guarantees, in writing, in plain language, that listed damage will be corrected?? ]
If I could find a product that has a guantee in plain lanuage there are usually so many exclusions.
It's your hard earned money, make your own choice but base it on prior knowledge of the product in question. "Let the buyer beware"
Research others opinions and products, test them and then make an objective decision based upon factual information not marketing hype or brand loyalty. I have always thought that the more facts and information you have at hand the easier it is to judge what information you are being given. After all, how can you fully understand and properly use any product unless you have all the facts?
