Okay, so almost all the important features were documented. This is actually one that was not assessed in the main section of this guide but that does not mean it is not important. In fact, it could be a deal breaker for some consumers. One of the benefits of electric models is that most often, they will be quieter than their gas-powered counterparts. But, that is not always going to be the case.
You see, part of the problem with some electric models is they can have a really annoying high-pitched whine. Some are enough to drive you insane and as a result, would probably cause you to return it. To be sure that a model is not going to be overly-loud, simply analyze the outputted decibel level of the unit (which should be provided by the manufacturer). Anything in the 60s is fairly quiet, as a point of reference.
