Bests & Worsts Reviews from Amazon

This trimmer is woefully inadequate. First off, the batteries last all of about 11 minutes on a full charge. I have fully charged BOTH batteries five times each. Ten full battery charges STILL haven't finished my 1/2 acre yard. Using a quality voltmeter, a fully charged battery reads approximately 20.8 volts. It becomes unusable and requires recharging at around 18 volts. The less-than-3-volts spectrum of usable power renders this product pretty much worthless. Further, the Auto-Feed System (AFS) string feeder uses WAY more line than a bump-feed trimmer. Again, without even having completed my yard ONCE, it has already chewed through a whole 30-foot spool of line. This is entirely unacceptable. Much of that 30 feet was completely wasted. Bump-feed trimmers hardly waste any line, as YOU decide when to let more line out. Portraying the AFS system as simpler than bump-feeders is ludicrous - really, how hard is it to bump the spool when needed? This Grasshog is going back to the store TODAY. Which is a darned shame - I'd much prefer a cordless trimmer to a corded or gas-powered model. But only if it WORKS, of course. I consider 2-stroke engines environmentally unfriendly, and a pain to deal with. But what's ultimately important is they WORK! I will be reluctantly replacing this Grasshog with a Troy-Bilt gas trimmer - tougher line (.095 instead of .065"), much more power, larger cutting swath, accessories-capable, and it won't die every 10 minutes!
