I have always been a fan of Black and Decker lawn tools, so I just recently purchased the GH600 electric grass string trimmer to add to my collection. I think it is a pretty decent tool for the money. It has good power, and the rotation head thing makes edging very easy. The big downfall of this grass trimmer is the fact that it uses a lot of string. The reason for this is because the string gets released automatically during operation, which would be convenient if it was calibrated properly. So make sure to protect your legs will using this trimmer, since string will be flying all over the place. What makes it worse it that it is not easy to put in new string, so I use replacements spools to save time. I think eventually I will replace the string spool with a blade attachment. This would probably make the GH600 electric grass string trimmer a great tool.
