Not much difference rating wise between the recommended units but WOW!!! there is a huge disparity between prices for almost similar performance. The running times on some of the units are scarily low as well, eg 6 minutes??? some double that, spare batteries needed? I would think so for our house.
Is it worth indicating how much an extra battery would cost in the reviews, for the ones where you can even swap the batteries out. Also if they come standard with a spare can this be searched on? If not it is it a lot of work adding that to the criteria to search on?
Worth becoming a CHOICE member to see the ratings and the savings on price could fund several years of full CHOICE membership (and I don’t mean just 2 or 3 years of membership).
