This Black and Decker cordless weed eater is balanced very well and uses a hefty string that does last and is easy to rewind on the spool. The battery takes the full 12 hours to recharge as listed in the instructions. The only drawback that I can see on this piece of equipment is that the charge only lasts for 25 minutes of weed eating. That 25 minutes is either in full speed mode or when throttling at a lower speed. The long charge time makes it so a person must have the mindset to do the 25 minutes of weed whacking and then find something else to do until the battery is recharged. This machine will cut anything that a gasoline engine driven weed eater will cut. I was very impressed with that and the fact that just a little bump will give you more string. I would buy this machine again but would buy 2 batteries to get more done in one day. (The charger will charge two batteries at one time.)
