superb battery life [SEP] videoid if you are not a reader like me the lawn mower will likely come with travel lock engaged simply tap the power button times to unlock after a full charge i have used the lawn mower a handful of times and still do not need to chargelawn mower seems to have a better value than the weed whacker so if you are debating on which bundle to buy the lawn mower is a great value on it is ownthe weed whacker does not have much power in my opinion i will likely return to my microtouch trimmer for ear nose trimming
