Well the stock echo style head on my Kawi trimmer took a dump Friday ( the white plastic piece inside started skipping, causing mega auto-advance) I tried to get the goodies to fix it Saturday, (the white bits) but they played dumb and said they didn't have the pieces. SOOO, I went down to Lowe's ( only place open on Sun.) and bought an Echo labeled Rapid Loader head. This thing is the biggest piece of S**T I've ever purchased!!! It is absolutelly useless. I trim for 5 mins max, more like 2 seconds if it's bad weeds, and the wreched thing breaks off the line. Then you better have frickin' needle nose pliers to get out the pieces.. So ya'll have been warned save you $25!!!!! Also I've noticed that the Husky T 35 head is awesome I know they sell it universal, but the package didn't say if it fits Kawi. I believe Kawi has an 8mm thread? Has anyone put that head on one please help.. If I knew for sure it would fit the !@#$% Loader would be in the dumpster in 30 seconds! Please help guys I gotto work tomorrow.
